Facebook Inc. is set to lead the biggest year for U.S. IPO's by Internet companies since 1999. According to Bloomberg, the industry may raise $11 billion next year. Facebook is considering the largest Internet IPO on record. Furthermore, regulatory filings show that at least 14 other web-related companies are planning sales.

According to industry insiders, Facebook is set to branch out into mobile advertising by the end of March 2012. This will give the company a new source of revenue ahead of its rumored IPO. The mobile ads will be featured in the mobile news feed as 'sponsored stories'. Facebook has recently been increasing its focus on mobile technology and paying close attention to the public's interest in smart phones and tablets. The social networking site expects its next 1 billion users to come mainly from mobile devices.
