Google's DoubleClick reports that Facebook has defeated 999 other web-related opponents on Google's list of top 1,000 sites. In the midst of all this success, Facebook's co-founder Mark Zuckerberg says he's "not making decisions to maximize the amount of money" that he's making and that one of the most transformative things to build in the world is "something that helps people share information and stay connected."

According to Google's Doubleclick, Facebook receives 570 billion pageviews per month, which is eight times as many pageviews as Yahoo, 15 times as many pageviews as MSN, and 72 times as many pageviews as Wikipedia. 

Google made the top sites list in order to step up display ad sales. The list shows the sites' category, page views, unique visitors, whether they have advertising and percent worldwide internet audience reach. The DoubleClick Advertiser Blog noted, "Our goal with the Top 1,000 Sites and other recent updates is to deliver new tools for greater planning efficiency and data to make more informed advertising decisions."

There's no doubt that Zuckerberg isn't surprised at Google's top sites results. Facebook has been his main focus ever since the young entrepreneur founded the social networking site in February 2004, and he insists  that his passion lies with helping to "make the world more open and connected," and that it's not about the revenue. 

"I don't actually know exactly what the external perception of this is," said Zuckerberg. "But I always read these articles that are like 'OK, you guys must be doing this because it's going to make you more money.' And honestly for people inside the company, that could not ring less true."

Zuckerberg went on to say that if he was doing this for money, he had the chance years ago to receive as much as $1 billion if he sold Facebook.

"We had this episode where Yahoo and Viacom were trying to buy the company. And it was really kind of this crazy time. Because we started the company as a dorm room project. 

"We reached a point where, you know, me and my friends, we were 22 years old, people were offering us a billion dollars or more for the company, and it's like - what do you do? Right? So we didn't want to sell the company. Obviously we didn't sell the company."

While Facebook topped the DoubleClick list for sites with advertisements, Google of course tops the list for top visited websites overall, with Yahoo in second place once again, and Youtube in third. On this list, Facebook falls to fifth place.
