In its IPO filing, Facebook revised its active user count up to 845 million, a significant jump from the 800 million that the company had listed on its site as recently as this afternoon.

According to the filing, about 483 million of those users use the site every day and the social network generates 2.7 billion likes and comments per day. Facebook has also become a huge repository for your memories: the site has 100 petabytes of photos and video stored on its servers.

And Facebook is using its access to that (voluntarily) captive audience. The majority of the company’s revenue comes from advertising — about $3.1 billion of its total revenue of $3.7 billion.

The remainder of the money comes from its payments system for its apps. Around 12 percent of Facebook’s total revenue comes from the social gaming company Zynga, which went public late last year.

The company is looking to expand even further, according to the filing. “[We] continue to evaluate entering China,” the company said in its filing, though with some trepidation. “However, this market has substantial legal and regulatory complexities that have prevented our entry into China to date.”

The company also indicated that it’s planning to continue its international expansion; Brazil and India were two of the countries with the biggest growth over the past year. The company is also looking to continue expansion in Brazil, Germany, India, Japan, Russia and South Korea. - Washington Post
