News of the social network's major milestone came via an interview with CEO Mark Zuckerberg published on Bloomberg Businessweek.  The billionth user was registered on Sept. 14, but Facebook did not publicly announce the achievement because of difficulties identifying the exact user.

Zuckerberg, who started the website out of his Harvard dorm room in 2004, has evolved Facebook over the past eight years to become a social staple on the web.  The commercial released today titled "The Things That Connect Us," celebrates the company's billionth user by reiterating the ubiquitous role it has achieved in people's everyday life.

Comparing Facebook to chairs, the ad implies the social networking site not only connects us through the internet, but unites us through a common need as vital as sitting down.

In the Businessweek interview, Zuckerberg went on to talk about the potential in Facebook's search capabilities.  The idea expands News Feed as something more than updates about your friends and promotions -- it will open up ways for browsing the entire Web.

From the interview: "The whole vision around News Feed was it should be like a newspaper and shouldn’t just be a list of posts your friends are making. I mean we should be able to really show you interesting trends and things that are happening. There are already trillions of connections between friend requests and all the content that’s being pushed into the system. At some point, that will start to be a better map of how you navigate the Web than the traditional link structure of the Web."
