The Entire D6 Interview With Facebook's Mark Zuckerberg and Sheryl Sandberg (3 of 4)

We’re posting all the interviews from the sixth D: All Things Digital conference that took place in late May.

But–as many readers have requested–they will all be available in their entirety in this column.

Here’s Part 3 of 4 of an interview I did with Facebook Founder and CEO Mark Zuckerberg and COO Sheryl Sandberg. (I will post one video part of the discussion with Zuckerberg and Sandberg every day this week, starting Monday and concluding tomorrow.)

The social-networking site has had quite a year as the hottest and most hyped on the Web 2.0 landscape. With fast growth and still-questionable monetization power, where Facebook is going will be a journey plenty will be paying attention to.

In this video, Zuckerberg and Sandberg talk about why Facebook is a technology and not a media company, as well as how to make money via advertising, how change is affecting the young company, the state of its relationship with both Google (GOOG) and Microsoft (MSFT), whether Facebook should sell or go the IPO route, and where the company will be in five years.
