According to sources, Jeff Dossett has taken a job at Demand Media as its SVP of Content Partnership Development.

That means Dossett, who has held top online jobs at both Yahoo and Microsoft, will be focused on content distribution partnerships for the online content company’s Demand Media Studio platform.

The Santa Monica, Calif.-based Demand, which sources said is now prepping its road show for its upcoming IPO, has been picking up big company execs to add to its roster.

In March, it hired Yahoo U.S. advertising sales head Joanne Bradford, who worked with Dossett at Microsoft.

When BoomTown last checked in with Dossett in mid-2009, he was leaving Yahoo for an adventure-focused start-up.

As its SVP for North American Audience, Dossett had been in charge of all of Yahoo’s media assets, including its powerful News, Sports and Finance content sites.

Dossett had joined Yahoo in late 2008, coming to the company from Microsoft, where he was MSN executive producer and general manager.

In his job at MSN, Dossett was the lead for audience, content and programming strategy and execution in the U.S.

He had worked at the company since 1991, in a variety of sales and marketing jobs in Canada, and later worked on strategy and business development for MSN.

Dossett was also CEO of Carpoint, now MSN Autos, and was GM of its real-estate arm.

He also took two years off from Microsoft in 2002 to climb the highest mountains on each of the seven continents, finally reaching the summit of Mount Everest in May of 2004.

Dossett reached the summit of Everest for a second time in 2008.

David Ko (pictured here), head of Yahoo’s mobile division, has added the Internet giant’s vast media properties in the U.S. to his portfolio, according to several sources.

BoomTown recently reported that Ko was the likely person to take over as North American Audience head at Yahoo (YHOO), reporting to U.S. EVP Hilary Schneider.

With purview over programming and more for the main Yahoo media properties, such as News and Finance, he fills a slot left by the departure of Jeff Dossett in May.

Since then, the key Yahoo content division has been run jointly by Jimmy Pitaro, who heads Vertical Audience Experiences for Yahoo, and Tim Mayer, who is in charge of Search & Social Applications, as well as the powerful homepage of Yahoo. Both now report to Ko, who joined Yahoo in 2000, sources said.

But, in a related move, product development for mobile has moved from under Ko to CTO and EVP of Products Ari Balogh.

A similar move of Yahoo’s media properties took place earlier this year, shifting key tech development responsibility to a global product organization at Yahoo’s HQ in Sunnyvale, Calif.

Previously, as had been the case in mobile, such development had been mostly carried out by individual media properties.

The argument for the shift posits that centralizing product development of Yahoo offerings drives efficiencies, saves money, eliminates redundancies and accelerates growth around the world.

Those who do not like the idea think it is wrong to separate the development of a product from programming because the two are intricately dependent and need to be tweaked delicately.

But, said one source, mobile has been deemed by CEO Carol Bartz as “part of the core” at Yahoo instead of more an experimental offering as it has been viewed internally.

Thus, mobile apparently needs to be closely aligned to all product development going forward.

Ironically, one of Yahoo’s more high-profile mobile efforts, its Yahoo Go mobile software application and portal, which was launched to much fanfare at the Consumer Electronics Show in Las Vegas almost four years ago, will be shuttered Jan. 12, 2010.

Now, under Ko, Yahoo’s mobile efforts have been centered around building apps for smartphones, although that market has become increasingly dominated by players such as Apple (AAPL) with its iPhone, Google (GOOG) and its Android effort and many others.

Google also just bought an innovative mobile advertising company, AdMob, which gives it a headstart in this nascent arena.

Without its own device and a dominating strategy, Yahoo must use its Web heft to push its content into the mobile space.

Presumably, that is the thinking behind giving Yahoo’s mobile and media properties the same boss.

Ko, who has worked in a variety of areas at Yahoo, took over as SVP of Yahoo Mobile after Marco Boerries left in late February as EVP of the Connected Device Division, which now does not exist under that name.

He had run Yahoo’s mobile business in the Asia Pacific region.

According to Ko’s Yahoo bio, he previously worked at Salomon Smith Barney as a senior associate and analyst. He is a graduate of New York University’s Stern School of Business.

Ko, who lives in San Francisco with his family, the bio notes, inexplicably “enjoys reading tech blogs.”

Well, then, Dave, we hope you have enjoyed this post!

Yahoo CEO Carol Bartz is making the most substantive changes in her exec ranks since she did a massive restructuring of its staff in late February, according to sources close to the situation.

“She is continuing to clean the place up,” said one top exec about the moves, which are likely to be announced internally tomorrow.

Among the shifts in management will be filling the slot left by the departure of North American Audience head Jeff Dossett in May.

UPDATE: Sources say Yahoo’s head of mobile, David Ko, will get the job of top Audience exec, although it is not clear if he will have the same portfolio has former media heads at Yahoo.

Since Dossett left, his job has been split between Jimmy Pitaro, who runs Vertical Audience Experiences, and Tim Mayer, who is in charge of Search & Social Applications. They both currently report to U.S. EVP Hilary Schneider.

The job of Audience head is a key role, given that Yahoo’s powerful media properties are among its most valuable assets. In recent months, Yahoo has made some major changes in the way it creates its juggernaut News property.

Also to be filled is the job being done by Corporate Partnership SVP Jim Schinella, who, as BoomTown previously reported, is set to leave at the end of the year.

I could not determine who will take Schinella’s job, inside or out.

Interestingly, Yahoo has yet to name an international head.

Sources said the company had filled the position, using a headhunter, but the London-based media exec candidate backed out at the last minute. That meant Yahoo had to restart its search.

There might also be other top exec changes, all part of Bartz’s consolidation of power at Yahoo. She has named a spate of new top execs from outside, but has also kept some from the regime of former CEO and co-founder Jerry Yang.

These staffing moves have come even as a stream of execs continued to depart the Silicon Valley Internet giant, including, most recently, Mike Walrath, who was SVP of advertising strategy. Walrath had led Right Media, the online ad exchange Yahoo bought for $680 million in 2007.

Walrath was widely expected to leave Yahoo in July, at the completion of his earnout from the acquisition, sources said, so the move was more sudden than expected internally.

Sources noted that Bartz moved Walrath’s departure forward in order to announce a new strategy for Right Media focused on premium publishers and to dump those ad networks and publishers of lesser ilk.

Whether this will stop the competitive onslaught in the ad exchange space is an open question given that Google has entered the fray significantly and that Facebook is widely expected to bolster its efforts.

Lastly, several sources said that there are also likely to be more changes on Yahoo’s board, which has seen the departure of two members recently.

In September, Maggie Wilderotter said she would leave the board by year’s end. And former Yahoo nemesis and investor Carl Icahn left the board in late October.

Whether Yahoo will replace them or keep its current size of 10 directors is not clear.

Also possible, several sources said, would be Bartz taking the chairman title, which is currently held by Roy Bostock. Bostock, along with Yang, played a key role in its botched takeover battle with Microsoft (MSFT).

Bartz finally successfully struck a sweeping search and advertising partnership with the software giant this summer, which is moving closer to being launched.

Yesterday, BoomTown broke the news that Yahoo’s SVP North American Audience, Jeff Dossett, was leaving the Internet company because of personal reasons.

But I also noted that sources said he was likely to quickly land at a start-up, and in fact, he has resigned from Yahoo to do just that.

Dossett, who came to Yahoo from Microsoft in November, is taking a job as CEO of AdventureLink, an online site aimed at adventure travel and booking such trips.

The Los Angeles-based AdventureLink is a good fit for Dossett, who is an avid mountain climber.

He took two years off from Microsoft (MSFT) in 2002 to climb the highest mountains on each of the seven continents, finally reaching the summit of Mount Everest in May of 2004.

Dossett reached the summit of Everest again for a second time last year.

Well-known adventurist Richard Bangs–who does content for Yahoo (YHOO), as well as television, and who serves on AdventureLink’s board–was involved in bringing Dossett on board.

Here’s the full press release:

ADVENTURELINK NAMES SENIOR YAHOO EXECUTIVE JEFF DOSSETT AS CEO

JEFF DOSSETT TO GUIDE ADVENTURELINK TO NEW HEIGHTS

LOS ANGELES (May 29, 2009)–AdventureLink, Inc., the world’s largest online source for booking adventure travel, today named former Yahoo! Inc. Senior Vice President Jeff Dossett as Chief Executive Officer. Mr. Dossett will be responsible for building global recognition for AdventureLink as the preeminent online marketplace for booking adventure travel.

In February 2009, AdventureLink launched the world’s first online booking system for adventure travel developed in conjunction with its partner, VAX VacationAccess. The AdventureLink system opens up booking capability for adventure travel opportunities worldwide providing easy access and distribution to over 70,000 leisure travel agents across North America.

Mr. Dossett joins AdventureLink from Yahoo! Inc., where he served as Senior Vice President, Audience Experiences, North America Region. Prior to joining Yahoo, Mr. Dossett was the Executive Producer & General Manager of MSN in the United States. He also served as CEO of Carpoint and General Manager of MSN HomeAdvisor.

In announcing Dossett as CEO, AdventureLink Chairman and Founder Kelly Tompkins states, “I love the fact that Jeff is a risk taker and an accomplished mountain climber, having summited Everest twice. But more than that, as an executive, he has demonstrated tremendous leadership both at Microsoft and, most recently, Yahoo.”

Samit Varma of Anthem Venture Partners explains, “We have been working to get Jeff on board for several months, and we’re thrilled to have him. He’s a perfect fit for AdventureLink. He brings not only a distinguished professional track record but also a personal passion for adventure travel.”

Mr. Dossett, a passionate adventurist, states, “I’m thrilled to join the AdventureLink team. It’s truly a unique opportunity to combine my personal passion for adventure travel with my desire to help build the world’s largest, most effective, online global distribution and reservation system for adventure travel. My ultimate goal is to help make it easier for consumers to discover, book, and experience life–changing adventure travel using AdventureLink’s technology.”

Richard Bangs, co-founder of Mountain Travel*Sobek and host of the PBS series, “Adventures with Purpose,” was instrumental in the choice of Dossett for CEO. Bangs, who serves on AdventureLink’s board of directors, has followed the company since it started three years ago.

“AdventureLink has created a unique model in developing the world’s first global marketplace for adventure travel,” states Mr. Bangs. “Over the years, I’ve seen AdventureLink grow by leaps and bounds due to its ability to develop unique technology as well as its ability to build strategic relationships within the travel industry. When Kelly invited me to join the board, I knew Jeff would be a great partner in helping Kelly realize his dream in making adventure travel accessible to everyone. Jeff’s passion as an adventure traveler and his executive experience with online media make for a perfect match in taking AdventureLink to new heights.”

Yahoo’s SVP of North American Audience, Jeff Dossett, is leaving the company.

Reasons for the departure are personal, said sources, who said that Dossett (pictured here) is most likely to do a start-up.

Dossett did not return emails asking for comment, but Yahoo (YHOO) confirmed the departure to BoomTown.

It was announced internally that Dossett has resigned and his responsibilities have been assumed by Jimmy Pitaro, who runs Vertical Audience Experiences for Yahoo, and Tim Mayer, who is in charge of Search & Social Applications. They will jointly lead the North America Audience business, reporting to U.S. EVP Hilary Schneider.

Dossett has been in charge of all of Yahoo’s media assets, including its powerful News, Sports and Finance content sites.

He has been rejiggering the media unit since he arrived last year, including centralizing product development.

Dossett joined Yahoo last November, coming to the company from Microsoft (MSFT), where he was MSN executive producer and general manager.

In his job at MSN, Dossett was the lead for audience, content and programming strategy and execution in the U.S.

He had worked at the company since 1991, in a variety of sales and marketing jobs in Canada, and later worked on strategy and business development for MSN.

Dossett was also CEO of Carpoint, now MSN Autos, and was GM of its real estate arm.

He also took two years off from Microsoft in 2002 to climb the highest mountains on each of the seven continents, finally reaching the summit of Mount Everest in May of 2004.

Dossett reached the summit of Everest again for a second time last year.

“It’s being changed every minute,” joked one Yahoo source about the reorg now in process at Yahoo, which is being shepherded by new CEO Carol Bartz.

Actually, it’s kind of true, as execs at the troubled Web company are being moved around the board like chess pieces, while other players are added.

According to numerous sources, mostly in Yahoo’s Sunnyvale, Calif. HQ, things are still in flux and not completely settled as yet.

But one thing is clear: Layers are being collapsed quickly, as fewer people are in charge of more, with all roads leading to Bartz.

Here’s the current lay of the land, in what is fast becoming Carol Country at Yahoo (YHOO):

Ari, Ari, Ari!

As BoomTown reported earlier this week, it looks like CTO Ari Balogh will be the biggest winner in the management restructuring, getting to ride herd over the entire product organization, both development and technology.

Most interesting is that Audience Product head and longtime Yahoo veteran Ash Patel is still staying–at this point at least–and report to Balogh (Patel had previously reported directly to outgoing President Sue Decker).

Many at Yahoo think Patel will eventually leave, even if he is not out in the current set-up.

But, if he stays, Patel will apparently focus more on product architecture, if he does remain, which is kind of the purview of Venkat Panchapakesan, EVP of the Audience Technology Group, who already reports to Balogh.

Superman exec Ari will surely sort it all out!

In this scenario, Front Doors head Tapan Bhat could get more product development responsibility, especially since media product development is being moved centrally under Patel.

Hilary Gets More Stuff

As someone perceived internally as a favorite of Decker, U.S. head Hilary Schneider seems to be scoring anyway.

She’ll run a new U.S. division, with media head Jeff Dossett under her, as well as advertising sales head Joanne Bradford.

Some Yahoos, though, think Bradford could report directly to Bartz, given her purview is the most important part of Yahoo’s business.

Schneider will also apparently get a much diminished Connected Life unit, which focuses on mobile and other devices, after the departure of its longtime head Marco Boerries.

I posted news of his leaving earlier today, which now means that part of Yahoo will not stand on its own as a separate fiefdom.

Who Is Joel Jones?

Indeed. Yahoo’s current VP of corporate strategy and former McKinsey consultant, Joel Jones (pictured here), is one of the nominees to be tapped to be Bartz’s chief of staff.

In the new, more centralized organization that Bartz is obviously creating, that will be much more than a bag-carrying role, to be sure.

“Joel is as sharp as they come,” said one former Yahoo. Sharp enough to help Bartz negotiate with Microsoft (MSFT) CEO Steve Ballmer?

No news on a possibly COO for Bartz, but she is getting a chief marketing officer to head up the brand and PR functions. Many are suggesting an exec like Pepsi-Cola North America interactive marketing exec John Vail, as I have previously reported, although Yahoo brand exec Allen Olivo is the internal candidate.

Also apparently staying for now is another Decker favorite, CFO Blake Jorgensen.

More to come!

[UPDATED: With Hearst press release confirming the move at the bottom.]

Neeraj Khemlani (pictured here), Yahoo’s general manager and executive editor of news, is set to leave his job–right in the midst of a major restructuring of its media unit–to work at Hearst Corp.

Khemlani’s departure was announced to his staff at Yahoo (YHOO) today and confirmed by the press release from Hearst below.

While Khemlani was in line to head one of the three main prongs of the new content organization, running a possible network programming arm, sources inside and outside Yahoo said he instead has opted to take a job as VP and Special Assistant to the CEO for Digital Media at Hearst.

Khemlani is not leaving due to the upcoming changes at Yahoo, said sources, but because he got a “compelling” offer to work for a more traditional media company in a range of businesses, from newspapers and magazines to broadcast, helping turbocharge their digital efforts.

Khemlani, who came to Yahoo from a long stint as a producer at the television news show “60 Minutes,” will be reporting to the privately-held media company’s vice chairman and CEO, Frank Bennack.

Khemlani, several sources said, told his bosses at Yahoo–U.S. Audience head Jeff Dossett and U.S. EVP Hilary Schneider–on Friday of his plans right when the pair were in the midst of planning a major shift in how media are managed and created at Yahoo.

At Hearst, he will be a resource for its many divisions, which all have their own digital operations, and he will be based in New York. (Khemlani currently has been working out of Yahoo’s media offices in Santa Monica, Calif.)

In a press release from Hearst, Bennack said: “Hearst’s major operating groups have all made substantial progress towards our corporate objective of fully participating in the digital transformation. The creation of this new position is designed to accelerate the progress through greater cooperation and synergy across divisional lines. Neeraj is uniquely equipped to help me and my colleagues realize that goal.”

Ironically, Hearst has a strong relationship with Yahoo, as a content partner.

UPDATE: In a Hearst press release Khemlani said: “I am delighted to join Hearst Corporation. We are witnessing the reemergence of content and media driving value in the new world and Hearst is uniquely positioned to realize that value across multiple digital platforms and distribution points. Remember, we’re only in the second inning of the Internet. Hearst, with all its assets and investments, expects to take a commanding lead by the seventh?inning stretch.”

As BoomTown reported yesterday, the management of the media unit is about to be rejiggered dramatically.

It’s part of big changes coming for Yahoo, including an even more massive management reorganization that new Yahoo CEO Carol Bartz could announce this week, as this column reported on Friday.

Under a plan being considered, the media unit will be split into three parts: vertical programming, network programming and search monetization.

This comes after some other recent changes in the way media product development is done–moving to a centralized global structure, rather than residing in individual media units–which was also reported here last week.

Now, if they go through with current plans to reorganize the media unit, Schneider and Dossett must find another head of network programming.

Several inside sources said that vertical programming will probably roll up under current Sports GM Jimmy Pitaro. And Tim Mayer–who is now VP of search monetization and distribution–would probably remain in his job, with perhaps even more monetization duties added.

Here is the Hearst press release about Khemlani:

HEARST CORPORATION NAMES NEERAJ KHEMLANI VICE PRESIDENT & SPECIAL ASSISTANT TO CEO FOR DIGITAL MEDIA

Hearst Corporation (www.hearst.com) is one of the nation’s largest diversified media companies. Its major interests include ownership of 16 daily and 49 weekly newspapers, including the Houston Chronicle, San Francisco Chronicle and Times Union; as well as interests in an additional 43 daily and 72 non?daily newspapers owned by MediaNews Group, which include the Denver Post and Salt Lake Tribune; nearly 200 magazines around the world, including Good Housekeeping, Cosmopolitan and O, The Oprah Magazine; 29 television stations through Hearst?Argyle Television (NYSE:HTV) which reach a combined 18% of U.S. viewers; ownership in leading cable networks, including Lifetime, A&E, History and ESPN; as well as business publishing, including a minority joint venture interest in Fitch Ratings; Internet businesses, television production, newspaper features distribution and real estate.

Besides the more massive management reorganization that new Yahoo CEO Carol Bartz could announce this week, as BoomTown reported on Friday, the Internet company’s powerful media arm might also see a drastic shift in management structure even sooner.

According to several sources inside the company, U.S. Audience SVP Jeff Dossett (pictured here) has been working on the changes for a while, part of an overall change in how Yahoo (YHOO) makes and delivers content. The new organization could be announced this week too.

Under a plan being considered, the media unit will be split into three parts: Vertical programming, network programming and search monetization.

It is not clear under this new set-up if Yahoo will keep its more traditional structure of having powerful general managers, each in charge of its big properties.

But that seems likely to be scaled back, at the very least, since the shift in management comes after some major recent changes in the way content is made, as was also reported here last week.

Already, the media group’s product development for all its major properties–such as News, Sports and Finance–is set to be moved to a central global product development organization at Yahoo’s HQ in Sunnyvale, Calif.

Until now, such development has been mostly done by individual media properties, many of which are located down south, in Santa Monica.

The argument for the shift posits that centralizing the product development of a Yahoo media offering drives efficiencies, saves money, eliminates redundancies and accelerates growth across the world.

Those who do not like the idea think it is wrong to separate the development of a product from the programming because the two are intricately dependent and need to be tweaked delicately.

Dossett will remain overall head of media efforts, but there is a lot of speculation inside the group about who will head the three new parts of media unit. But that is still being worked out by Dossett and his boss, U.S. head Hilary Schneider, and is still not decided.

But several inside sources said that vertical programming is probably a lock to roll up under current Sports GM Jimmy Pitaro.

Former “60 Minutes” producer and News GM Neeraj Khemlani seems be the most likely candidate to head network programming, but that is not yet complete.

And Tim Mayer–who is now VP of search monetization and distribution–would probably remain in his job, with perhaps even more monetization duties added.

Several sources inside and outside Yahoo told BoomTown that new Yahoo CEO Carol Bartz could be ready to announce a major reorganization of its management structure as early as next week, most likely on Wednesday.

While that shift could be pushed out a week or two or rolled out in pieces, Yahoo (YHOO) execs are nervously awaiting the moves by Bartz to put a new regime in place in order to more easily power through a massive reset of the troubled company.

Interestingly, many top execs are very much in the dark about what Bartz will do since she manages very close to the vest, mostly moving around Yahoo with only her longtime executive assistant in tow.

Thankfully, she also loves to write detailed memos to the staff, and she signaled the “big week” ahead in one Boomtown just obtained (see here) that was sent out today.

Those are code words for reorg, according to many sources I spoke to, coming after Bartz has spent a lot of time visiting many parts of Yahoo and conducting a whirlwind of meetings with execs.

I will be posting my Heidi-Klum-you’re-in-and-out predictions of the fate of various execs later this weekend.

But broadly, most expect Bartz to severely roll back a variety of previous reorganizations done by former CEO Jerry Yang and former President Sue Decker.

That will mean many top execs will likely be quite out–already, Decker’s chief of staff, Jeff McCombs, has quietly departed the company, several sources said–while others will be elevated.

Most sources I spoke to who have interfaced with Bartz think she will likely go with a more traditional and more accountable structure like the one she employed while rehauling Autodesk (ADSK), the computer-aided design software company she once headed, rather than the matrix-tangled Yahoo.

A change in how Yahoo makes media, which I wrote about today and was approved by Bartz, is a classic globally-centered development organization. (By the way, a significant reorg of the media organization, headed by Jeff Dossett, is also set for next week, said sources.)

Thus, most expect Bartz to do a C-level-style set-up, with execs like a COO, CTO and a new, more powerful CMO (who will also head PR), all reporting to her.

In addition, several suggested she might also junk a recent reorg that split the world into four regions. Instead, one exec could head the U.S., where most of Yahoo’s current business is, and one head international efforts.

Whatever happens, it’s clear that “Hurricane Carol”–a nickname she has been given by some employees in admiration–is getting ready to blow right through Yahoo.

Batten down the hatches–more to come…

Will Yahoo’s media properties fall flat with sweeping new changes that are afoot that will drastically change the way the company bakes its content offerings?

Or will the ability to have a single, highly scaleable, centrally developed architecture make the media programming Yahoo delivers more responsive and flexible in the era of fast-twitch bloggers (all while cutting costs)?

According to many sources inside and outside the company, product development for Yahoo’s heavily trafficked media operations–including its powerful News, Finance and Sports sites–is set to be moved under Ash Patel, who is EVP of the company’s Audience Product Division.

The move has been supported by U.S. Audience head Jeff Dossett, who came to Yahoo (YHOO) from Microsoft (MSFT). He replaced former media head Scott Moore, who is about to take over content efforts at Microsoft.

The centralization of product development for the media properties was much resisted by Moore and by many managers within Yahoo’s media group, who are worried and unhappy about the upcoming change.

Sources told BoomTown that it is one of many changes coming to the unit, which is likely to soon get a dramatic management restructuring too.

Under the new configuration, which sources said had been approved by CEO Carol Bartz, media products–but not editorial programming–will be developed “globally” at Yahoo’s Sunnyvale HQ in Northern California.

Until now, such development has been mostly done by individual media properties, many of which are located down south, in Santa Monica.

But a move to global product and platform development has been steady at Yahoo for a while. The move to change how media are made was initially championed by former President Sue Decker, but has continued to move forward after she announced in January that she planned to leave the company.

As with most things, there are pros and cons to the new approach.

The pro argument posits that centralizing the product development of a Yahoo media offering drives efficiencies, saves money, eliminates redundancies and accelerates growth across the world.

Said one on-the-bandwagon exec to me in an email: “This is a good and smart plan to achieve better balance between the benefits of a globally scalable product development and the need for regions to be very close to and responsive to local user and advertiser needs…there is huge upside (in user engagement and monetization) that will come from a deeper focus on editorial, content (original and licensed) and programming within the properties and most importantly across the network.”

Those who do not like the idea think it is wrong to separate the development of a product from the programming because the two are intricately dependent and need to be tweaked delicately.

In addition, they argue, it makes Yahoo media offerings, which have been largely successful, less unique and more dull.

“It’s like separating the cook from the recipe and ingredients,” said one person who thinks that it’s very hard to separate product from the content online. “You could end up with a really bad cake.”

Translation: I don’t think that I can take it/’Cause it took so long to bake it/And I’ll never have that recipe again.

Whatever the case for Yahoo’s media properties, I think we can all completely agree that this Donna Summers rendition of “MacArthur Park” remains as fresh and delicious as ever (plus it’s a karaoke video version, so feel free to sing along):

Just after he got the job 10 days ago, BoomTown got the chance to chitty-chat a bit with Scott Moore (pictured here), the former Yahoo media chief, who is returning to Microsoft, where he will lead online content efforts in the U.S for its MSN online service.

Apparently, you can go home again!

It’s a touché tale because it feels like Moore was pretty much rehired by MSN exec Greg Nelson (also in on the conversation with Moore) to give Yahoo a wallop where it really will hurt–its powerful content business, one of Yahoo’s few bright spots.

And to add another layer of irony, Moore replaced Jeff Dossett, who replaced Moore at Yahoo (YHOO) after Moore suddenly left the troubled online company late last year.

In our conversation, Nelson began talking first about the continued commitment of Microsoft (MSFT) to compete in the online media business despite its lackluster record over the years.

“We are making a big bet with Scott because he understands the key themes for us, which is that this is a scale business,” said Nelson (pictured here). “We all have a conviction that Microsoft has what it takes to compete in that arena.”

Moore agreed, noting that “very few companies have the scale that Microsoft has and you look at the size of the audience and the tools and great assets we can weave in and you realize the possibilities as the market is changing.”

But that scale has not helped Microsoft so far, although Moore argued that it still has a chance as the online content landscape changes.

By change, Moore posits that the Internet is now shifting from being a place to get news and information to becoming a primary entertainment medium.

“You can see that phenomena is somewhat in social media, the idea that it is not only about entertainment, but about making all kinds of choices through the Internet,” he said.

Because of Microsoft’s large audience, which still lags behind Yahoo and Time Warner (TWX) online service AOL, Moore thinks it has the opportunity to leverage the distribution strength with a variety of entertainment partners.

But he said he is not ruling out more original content from Microsoft.

“Most of it is still aggregated content, but MSN also has to think about having stuff no one else has,” Moore said. “You can make it, license it or partner.”

Both Moore and Nelson said it is important that the small amount of premium content is special, such as Microsoft’s deal with NBC during the Olympics.

“It’s a pyramid with the original and premium content on top,” said Nelson.

That does not mean going too far afield though. “I think we have to choose a spot where we already have a large audience and then program to keep them coming back,” said Moore. “It’s not doing something out of whole cloth–that’s not the idea.”

That’s presumably the exact idea behind MSN’s launch of Wonderwall last week, a slick, standalone celebrity Web site (pictured here), designed to compete with AOL and Yahoo offerings.

Moore, who was involved with the creation of Yahoo’s top-ranked omg! pop culture site, was not part of the Wonderwall effort and he did try to tamp down the idea of going head-to-head with former colleagues at Yahoo.

“I have a lot of friends and a lot of great memories there, but it is also great to go back to my roots,” said Moore.

Nonetheless, he still managed to add that he wanted to get MSN sites to top status as soon as possible. “When I got to Yahoo it was not No. 1,” he said.

Nelson said Microsoft was committed to content, even after a history of less-than-stellar results.

“Ideas are free, and so it is all about execution,” said Nelson. “What is our level of conviction? How committed is Microsoft? Very committed, because it’s the future of the company.”

The game of executive musical chairs among Web companies keeps on going, with sources telling BoomTown that AOL ad head Lynda Clarizio will be departing the online service and replaced by former high-ranking Yahoo ad exec Greg Coleman (pictured here).

Last week, this column first reported on former Yahoo media head Scott Moore taking a similar content job at Microsoft (MSFT), which had been vacated by Jeff Dossett, who took Moore’s job at Yahoo.

The less confusing move at AOL, with Coleman taking over for Clarizio and which has been in the works for only a week, could be announced as early as today, although I have been hearing rumors of such a development since late last week.

Clarizio has been head of Platform-A, the overall name for AOL’s advertising business, which includes a lot of various online ad companies AOL has bought in recent years.

She had been running AOL’s Advertising.com in Baltimore before being tapped to integrate them better over the last year, after a series of ad execs shuffled in and out of AOL.

But, said several sources, as a former AOL lawyer and dealmaker, Clarizio (pictured here) is not regarded by top execs the kind of nitty-gritty sales exec that AOL needs now, as it seeks to revive its fortunes.

AOL’s ad business has lagged badly of late, with owner Time Warner (TWX) pre-announcing that the online service’s results would be particularly weak this quarter. Time Warner reports quarterly earnings tomorrow.

Since a much-chewed-over possible merger with Yahoo (YHOO) has been put on ice, with the recent arrival of new CEO Carol Bartz, Time Warner and AOL execs have decided to focus on strengthening the online service and making much needed changes.

AOL recently announced a 10 percent layoff of its staff of 7,000, part of the rightsizing that has been going on.

And its valuation was also recently written down by Google (GOOG), to $5.5 billion from $20 billion several years ago.

AOL had already been in the midst of renovating its communications and social-networking assets under a new division called People Networks, which is run by former Bebo head Joanna Shields.

Its content arm has also gotten a different blog-centered direction and name–MediaGlow–under Bill Wilson.

Now, it’s apparently time for the ad leg of AOL’s three-pronged new strategy its future business is resting on to be fixed.

The hiring of Coleman came suddenly, said several sources. He had been considering a top job at another well-known online company and also was planning to move to a start-up he has been running to the Silicon Valley area.

He was hired by AOL CEO Randy Falco, whom Coleman has known for a long time, only last week, after Falco heard that Coleman was considering other positions.

Sources at Yahoo said the hiring had to be cleared by the company and Bartz, at Time Warner CEO Jeff Bewkes’s request, due to competitive issues.

Coleman is indeed an experienced online ad exec, who was at Yahoo for seven years, responsible for all advertising revenues worldwide. He came to Yahoo from Reader’s Digest.

But Coleman ran into Yahoo’s management buzzsaw after trouble hit the company in 2007. He was one of the first in a long line of execs to leave the troubled company, departing in one of its many controversial reorganizations.

But Yahoo’s ad business did grow strongly under him and former Yahoo ad exec Wenda Millard. She was also pushed out of Yahoo and now is Co-CEO of Martha Stewart Living Omnimedia.

Since then, Coleman has been running a Los Angeles-based start-up called NetSeer, which focuses on ad targeting.

Given his media background, Coleman is likely to be key to expanding premium branded advertising display sales across AOL’s advertising and programming networks.

He will move to New York and report to AOL President and COO Ron Grant, said sources, although Platform-A has key offices in Baltimore and San Francisco too.

In an unusual homecoming and odd job switcheroo between two Internet execs, former Yahoo media head Scott Moore is returning to Microsoft to lead its U.S. content efforts, according to many sources both inside and outside the company.

Moore (pictured here) will become U.S. executive producer, responsible for leading the content and programming strategy for the MSN online service. He will return to Microsoft’s Seattle area HQ in mid-March and report to Greg Nelson, GM of the MSN Global Media Group.

Microsoft (MSFT) declined comment about Moore’s new job, but sources said news of the appointment will be officially announced Monday.

But a memo about Moore’s new gig went out internally to some of the MSN staff earlier today, sources said. In fact, the return of Moore had been widely rumored inside Microsoft, even though there were several other internal and external candidates considered–including another former Yahoo, one source said–for the job.

Moore left Yahoo (YHOO), which was first reported here, last November due to unhappiness over the turmoil at the company and also to pursue a start-up idea he had about a local news site.

Moore even talked about the idea on the record with BoomTown (see video below), just as he was leaving Yahoo’s Santa Monica-based Media Group. Since he left Yahoo for good in December, Moore has been working on his start-up plans and took time off to go on a safari trip to Africa.

(Here’s a link to Moore’s Africa photos, in fact, which are quite good.)

But with the economic downturn making it harder for new start-ups to get funded on good terms, a desire to be back in the Seattle area, where his children live, and a new effort by MSN to compete better in the content business with top-ranked Yahoo, sources said Moore felt the powerful job at Microsoft would be a terrific challenge.

In what is a case of Web exec musical chairs, Moore had previously been replaced at Yahoo–in a rushed appointment–by Jeff Dossett. Dossett came to Yahoo from, wait for it, Microsoft, where he had held the job Moore is now taking.

In that move, also first reported here, Dossett was given a different title at Yahoo than Moore, as SVP of the U.S. Audience Group (Moore was SVP of the Media Group at Yahoo).

When he first started talking to Yahoo, Dossett (pictured here) was actually up for a job to run business development for Yahoo. But Moore’s sudden decision to leave had his boss, Yahoo’s EVP of U.S., Hilary Schneider, scrambling to fill the post. Dossett’s experience at MSN made him the obvious choice.

Now Moore’s appointment puts the pair in head-to-head competitive positions in the online content business, a clash that has been consistently won by Moore, when he had Dossett’s job at Yahoo and Dossett had Moore’s job at MSN.

Moore should also be comfortable at Microsoft and move into his job more easily. Previous to coming to Yahoo in mid-2005, he was president of MSNBC.com and publisher of Slate.com. He had worked at Microsoft for a decade.

Moore will oversee Microsoft’s involvement in the MSNBC.com joint venture again, along with all of Microsoft’s domestic content programming, which makes up a bulk of its efforts in the area.

And with Moore back on board, how MSN will better compete with the content juggernaut Yahoo is–due to Moore’s efforts, in part, and one of the troubled company’s stronger units–will be interesting.

That’s because Yahoo’s news, finance, sports and other properties typically rank as No. 1 online by far.

Time Warner (TWX) online unit AOL has also tried recently to improve its content offerings and has gotten some traction. It recently upped the ante with its new MediaGlow online studio effort of niche blog sites.

At the very back of this pack, Microsoft has made innumerable efforts in the content space over the years, mostly unsuccessful–Underwire!, Mungo Park!–and has settled more into the aggregation model.

But it still has a lot of interesting original content efforts under way, such as an unnamed celebrity-focused site property it is reportedly launching within the next week with former Yahoo media exec–and Moore’s former boss–Lloyd Braun.

Ironically, Moore launched a Yahoo celebrity site, omg!, initially pushed by Braun when he was at Yahoo, which has been successful.

Here is the video interview I did with Moore at his Yahoo going-away party about his future plans. Below that is another one I did when he was czar of Yahoo content, in which he talked extensively about the future of content on the Web.

As BoomTown reported earlier today in detail, Yahoo will announce its layoffs on Wednesday, as planned, of at least 1,500 employees.

But many staff have also been leaving Yahoo on their own, including one recent high-profile departure–now former Yahoo Media Group SVP Scott Moore.

Moore’s been replaced by former Microsoft exec Jeff Dossett, whose title is now as U.S. audience head.

Moore–who came to Yahoo in 2005, after leading a lot of content efforts at Microsoft (MSFT)–does not have firm plans, although he has been working on a stealth start-up idea.

(With former Yahoo tech exec Qi Lu headed to Microsoft, it was revealed here last week, talk about revolving doors between the two companies!)

While he would not comment on the turmoil at Yahoo, Moore did have a lot to say in an interview I did with him on the night of his Yahoo going-away party in Santa Monica last week.

In it, Moore talks about where online content is going–and also where he is headed (first of all, he is going on a trip to Africa).

(See an earlier video I did with Moore, back in July, about similar topics below.)

Here’s the new video and the older one below it:

Yahoo–which has stuck to its guns by staying in the search business, even though many think it is a losing game and should be sold off to Microsoft–has lost a key engineer in that arena to, uh-oh, Microsoft.

Sean Suchter, the VP of Search Technology at Yahoo, was also deeply involved in Yahoo’s efforts to open up its search platform, initiatives the company has touted aggressively as a bright spot in its not-so-lustrous landscape.

The departure of Suchter–who came to Yahoo (YHOO) almost six years ago after it acquired Inktomi (the company that got Yahoo into the search business) in early 2003–has been in the works for a while and was not linked to this week’s announcement that Yahoo CEO Jerry Yang will be stepping down.

Yahoo confirmed Suchter’s departure, but Microsoft (MSFT) has not yet announced his arrival there.

[UPDATED: Microsoft has now officially announced that Suchter is coming to the company.]

But sources said it will be in late December, with Suchter will be working in search for Satya Nadella, the SVP who heads engineering for Microsoft’s search, portal and advertising platform group.

Sources at Microsoft had told me of that they were close to locking down this impressive get several weeks ago. “If we can get someone like Sean, it says a lot,” said one source.

Indeed, Suchter has been an important tech leader at Yahoo, much as Qi Lu–the well-regarded Search and Advertising Technology group EVP, who left earlier this year–was.

In his LinkedIn profile, Suchter noted about his duties at Yahoo:

“I run Yahoo’s Web search engine, with overall responsibility for its success. This includes engineering, product responsibility, operational stability, results quality, capex spending and revenue (from the paid inclusion program).”

There are big questions, now that Yang is stepping down, whether Yahoo will stay in the search business or sell it off. Yang has been a big proponent of doubling down in search, considering it integral to the entire Yahoo ecosystem.

But others make the very persuasive argument that Yahoo will be increasingly outspent by both Google (GOOG) and Microsoft, in what is turning into a very vicious and expensive arms race.

If it sold off its No. 2 search business to Microsoft–ironically, Yahoo used to deliver Microsoft’s search results–many think it could have huge costs savings and garner guaranteed revenues.

News of Suchter’s departure, including the internal Yahoo memo announcing it, appeared in Valleywag this morning, which speculated that Suchter was headed to Microsoft.

In the memo, Tuoc Luong, Yahoo’s SVP of Search, stated the very obvious about Suchter’s departure:

“Unfortunately, I have to give some bad news to you. Sean Suchter has resigned. Sean’s last day will be December 19th.

Some of you will find this news shocking given that Sean has been a Gibraltar rock at Yahoo and in particular for the Search team. I understand this.”

Interestingly, Yahoo has recently nabbed several of former Microsoft execs, including U.S. ad head Joanne Bradford and U.S. Audience SVP Jeff Dossett.

Please see this disclosure related to me and Google.

Here’s my favorite quote from former Microsoft exec Jeff Dossett from a phone interview he gave to BoomTown this afternoon, after his appointment as Yahoo’s new U.S. Audience head:

“Where others see risk, I see opportunity,” said the man who has climbed Mount Everest twice. “We have this great Web asset … and, from here on out, it is all about execution.”

(Speaking of which, the photo above of Dossett is on the summit of Everest, taken by one of his TEAM INSPIRED climbing partners, David Morton, on May 22, 2008.)

You can tell from the gumption in this ain’t-no-mountain-high-enough sentiment that Dossett just got to Yahoo (YHOO) and sees a challenge at the troubled Internet giant where others see, well, a long-running quagmire.

I like him already!

“If you take a look at it, Yahoo has so many incredible assets,” said Dossett, who is replacing Yahoo Media Group SVP Scott Moore, whose departure from Yahoo was reported here first today. “There is an unparalleled level of audience to build on.”

You won’t get an argument from me on that obvious fact, because amazing content and communications assets have always been Yahoo’s crown jewels.

It’s the management–or lack thereof–of its products and staff by Yahoo’s leadership and board that’s been the problem.

So it is probably a good idea that Yahoo has brought in new blood to shake things up more. Yahoo CEO Jerry Yang has been looking outside the company of late to recruit outside talent.

Dossett was one of these execs, as I had written a month ago in a post titled “The Secret Microsoft Invasion of Yahoo Continues: MSN GM Headed There Soon?”

With its stock in the perpetual doldrums, the graphical advertising business outlook glum and a lucrative search ad deal with Google (GOOG) trapped in a Justice Department lockbox, the company could use someone to rattle its cages.

In the interview, Dossett (pictured here) acknowledged that he had been speaking to Yahoo U.S. head Hilary Schneider about a range of jobs related to business development. But when Moore told Schneider he was leaving, “We both thought I might be able to play a larger role.”

Dossett said that he hoped to be able to continue to keep Yahoo the No.1 or No. 2 content destination over a range of categories and also push forward more integration with Yahoo technology offerings such as email, calendar and others popular consumer tools the company has.

“There is a tremendous need to integrate … to create the largest and most engaged online audience,” he said. “It all still needs to be stitched together.”

Well, it has not exactly been a very successful quilting bee as yet. Yahoo has continued to struggle to make a more seamless offering to meet the changing needs of consumers, many of whom have been moving more toward more integrated social-networking experiences like those offered by Facebook.

“There is so much more we can do,” said Dossett. “We have only really scratched the surface to combine what we have.”

Dossett, who said his departure from Microsoft (MSFT) was cordial, would not comment on what a combination of Yahoo with the assets of Time Warner (TWX) online unit AOL would look like though.

Yahoo and AOL have been engaged in long-running talks about a merger, a new company in which Dossett would now play a large role, if a deal was ever to be struck.

It will be a big challenge that will surely test Dossett, a longtime and experienced mountain climber, who has spent much of his career at Microsoft.

That includes during the period over the last year in which the software giant was trying to take over Yahoo without being too polite about it.

In his job at MSN, Dossett was the lead for audience, content and programming strategy and execution in the U.S.

He had worked at Microsoft since 1991, in a variety of sales and marketing jobs in Canada, and later worked on strategy and business development for MSN.

Dossett was also CEO of Carpoint, now MSN Autos, and was GM of its real estate arm.

At Yahoo, he joins another former Microsoft big shot and close colleague, Joanne Bradford, who started her job as Yahoo’s top U.S. ad sales exec last month.

Dossett also took two years off from Microsoft in 2002 to climb the highest mountains on each of the seven continents, finally reaching the summit of Everest in May of 2004.

Dossett reached the summit again for a second time this past May.

Somehow, I think he will find the air at Yahoo just as thin.

About a month ago, BoomTown reported that MSN executive producer and general manager Jeff Dossett (pictured here) was contemplating joining Yahoo.

Microsoft (MSFT) released a statement that day saying Dossett was indeed stepping down from his MSN duties, as I had posted, but noted that he was staying put at the software giant.

Oops, it looks like I was right in my initial report: “The Secret Microsoft Invasion of Yahoo Continues: MSN GM Headed There Soon?”

Dossett has accepted a job as SVP, U.S. Audience at Yahoo, Yahoo (YHOO) said in a press release this afternoon.

“I am very excited about this new leadership opportunity at Yahoo,” wrote Dossett in an email to me. “Of course, I have great respect for my many friends and colleagues at Microsoft and I wish them well.”

But is the hire linked to my report earlier today of Yahoo Media Group SVP Scott Moore leaving?

You betcha, as Governor Sarah Palin says.

While the company had already been deep in conversations with Dossett for another job, as head of business development, management scrambled after Moore reportedly told Yahoo of his plans to leave a week ago.

After BoomTown this morning reported that Moore, as well as Yahoo News general manager Alan Warms, were departing later this week, Yahoo confirmed the departures this afternoon.

Dossett will report to Hilary Schneider, executive vice president of Yahoo U.S., and fill the role previously held by Moore, although the title is different. Yahoo said Moore was leaving “to pursue other opportunities.”

A Yahoo spokesman also said later about Warms:

“We’ve worked with Alan over the last couple of months on an orderly transition plan of his responsibilities over to Neeraj Khemlani, who will continue to lead Programming & Development for News & Information at Yahoo. We wish Alan much success in his future endeavors and know that Neeraj will continue driving Yahoo News to even greater success.”

Dossett will have presumably have purview over all that and more.

A longtime and experienced mountain climber, he has been one of the more senior digital execs at Microsoft.

The reason given for Dossett’s departure from Microsoft, announced internally in mid-September, was to also “pursue other opportunities” (I still love this phrase, as oily as it is.)

As I wrote then: “While the hire is not yet complete, that apparently means that he is likely going to rival and onetime Microsoft quarry Yahoo as a senior exec.”

It has all been an interesting digital-musical-chair trend, in fact. Also last month, another former Microsoft big shot, Joanne Bradford, started her job as Yahoo’s top U.S. ad sales exec.

Bradford came to Yahoo after a very short stint as national ad sales head at the trendy Los Angeles start-up, Spot Runner.

Previous to that, Bradford (pictured here) had been at Microsoft for many years, most recently as VP and chief media officer of MSN Media Network.

While at Microsoft, Jeff Dossett was a close colleague of Bradford, so his moving to Yahoo is probably not that much of a surprise.

Outgoing Yahoo Media Group SVP Moore, who has been at Yahoo since 2005, is another former Microsoft digital exec, where he worked all over the company.

In his job at MSN, Dossett was the lead for audience, content and programming strategy and execution in the U.S.

He had worked at the company since 1991, in a variety of sales and marketing jobs in Canada, and later worked on strategy and business development for MSN.

Dossett was also CEO of Carpoint, now MSN Autos, and was GM of its real estate arm.

He also took two years off from Microsoft in 2002 to climb the highest mountains on each of the seven continents, finally reaching the summit of Mount Everest in May of 2004.

Dossett reached the summit of Everest again for a second time this past May.

Here is Yahoo’s press release about his appointment in its entirety:

JEFF DOSSETT JOINS YAHOO! TO LEAD US AUDIENCE BUSINESSES

In 2002, Dossett took two years away from his career at Microsoft to pursue his passion for adventure with a goal to climb the highest mountain on each of the seven continents, known as the “Seven Summits.” Reaching the summit of Mount Everest on May 24, 2004, Dossett became the third Canadian in history to successfully complete the Seven Summits. On May 22nd, 2008, Jeff became the second Canadian in history to reach the summit Mount Everest for the second time. He serves on the Board of Advisors of VillageReach (www.villagereach.org), GOOD Worldwide Inc. (www.good.is), and Live Mocha (www.livemocha.com). Dossett holds a degree in business administration with honors from the Richard Ivey School of Business at the University of Western Ontario in Canada.

A longtime and experienced mountain climber, Dossett (pictured here) has been one of the more senior digital execs at Microsoft.

The reason given for Dossett’s departure from Microsoft (MSFT), announced internally this afternoon, was to “pursue other opportunities.”

While the hire is not yet complete, that apparently means that he is likely going to rival and onetime Microsoft quarry Yahoo as a senior exec.

It is an interesting digital-musical-chair trend, in fact. On Monday, another former Microsoft big shot, Joanne Bradford, will start her job as Yahoo’s top U.S. sales exec.

Bradford came to Yahoo (YHOO) after a very short stint as national sales head at the trendy Los Angeles start-up, Spot Runner.

Previous to that, Bradford (pictured here) had been at Microsoft for many years, most recently as VP and chief media officer of MSN Media Network.

While at Microsoft, Jeff Dossett was a close colleague of Bradford, so his moving to Yahoo would not be that much of a surprise.

But one has to wonder what other Microsoft execs Bradford can entice to come to Yahoo, especially given that CEO Jerry Yang is reportedly interested in aggressively beefing up his executive ranks after more than a year of employee attrition due to all the turmoil at the company.

Current Yahoo Media Group SVP Scott Moore, who has been at Yahoo for several years now, is another former Microsoft digital exec.

What Dossett would do if he takes a job at Yahoo is unclear.

But, in his job at MSN, Dossett was the lead for audience, content and programming strategy and execution in the U.S.

He has worked at the company since 1991, in a variety of sales and marketing jobs in Canada, and later worked on strategy and business development for MSN.

Dossett was also CEO of Carpoint, now MSN Autos, and was GM of its real estate arm.

He also took two years off from Microsoft in 2002 to climb the highest mountains on each of the seven continents, finally reaching the summit of Mount Everest in May of 2004.

Dossett reached the summit of Everest again for a second time this past May.
