It’s not all departures!

Yahoo is hiring former News Corp. and Disney online exec Mickie Rosen (pictured here) to run its Audience unit, which includes the Silicon Valley Internet giant’s powerful content sites, sources said.

Starting next week, Rosen will report to Americas head Ross Levinsohn, who has worked with her before, at both News Corp. and Fuse Capital.

Her new title is SVP of the Yahoo Media Network, which is apparently a rebranding of Audience.

Previous to this job, Rosen was CEO of Tecca, a price-checking service Fuse created in partnership with Best Buy.

It’s likely she will remain based in the Los Angeles area, where Yahoo has a large office in Santa Monica, Calif.

The move is Levinsohn’s first management rejiggering since he took over last year, and there is likely to be more to come.

Rosen, who has also worked at the Fandango online movie ticketing site, will replace interim audience head Raymond Stern, who will be–as before–running partnerships and business development, as well as Yahoo’s listings business.

Rosen’s new job had actually been that of former Audience head David Ko, as well as former Media VP Jimmy Pitaro.

Ko left Yahoo and is now heading mobile games at Zynga, while Pitaro is a top digital exec at Disney.

More to come from Levinsohn, but here is Rosen’s bio from the Fuse Web site:

Mickie has over 20 years of operating, strategy and investing experience. For the past dozen years, she has been at the intersection of media and technology, in both large companies such as News Corporation and The Walt Disney Company and in small, early stage start-ups.

Prior to joining the firm, she was the head of entertainment for Fox Interactive Media where she was responsible for properties such as AmericanIdol.com, Rotten Tomatoes and the entertainment channels of MySpace. Mickie also led content acquisition across the Company, and was a lead in envisioning, structuring and negotiating Hulu, the premier video joint venture between News Corp. and NBC Universal.

Prior to Fox Interactive Media, Mickie was the head of product development, marketing and public relations for Fandango, where she helped lead the company from an early-stage start-up to profitability as it became a leader in its space (acquired by Comcast). Mickie was also a senior executive with an e-learning start-up, an Idealab! consumer robotics company and Disney’s Corporate Alliances group, where she negotiated deals and managed Disney’s top global partners such as Coca-Cola, American Express and AT&T.

Mickie built the foundation of her career with McKinsey & Company, where she spent seven years consulting with senior management on strategy, operational and organizational issues across a number of industries, including media and technology.
Mickie has an MBA from Harvard Business School, and a B.A. in Economics from UC San Diego, and is based in Los Angeles.

Consider this: Using the Storm botnet and 75,869 of its zombie members, researchers at UC Berkeley and UC San Diego broadcast 350 million pieces of spam peddling male enhancement supplements. All but 28 were ignored. “After 26 days, and almost 350 million e-mail messages, only 28 sales resulted,” the researchers explained. “Taken together, these conversions would have resulted in revenues of $2,731.88–a bit over $100 a day for the measurement period.”

That’s a conversion rate of well under 0.00001 percent. Laughable, right?

Not really. The supplements were priced at $100. And botnet overhead, as you might imagine, is quite low. Which means it’s entirely possible to turn a nice profit by managing just one sale per 12.5 million emails sent. Said the researchers, “Under the assumption that our measurements are representative over time, we can extrapolate that…Storm-generated pharmaceutical spam would produce roughly $3.5 million dollars of revenue a year.”
