Tools

More than half of all Americans over the age of 12 are now on social networking platform Facebook, according to a new report conducted by Arbitron, Inc. and Edison Research. As of January 2011, 51 percent of Americans maintain Facebook profiles, up from just 8 percent only three years ago.

Credit Facebook's popularity among mobile subscribers for its continuing growth: More than 200 million consumers are now actively using Facebook's mobile products across all platforms, increasing from only 65 million a year ago. In addition, Facebook is the most popular application across most operating systems according to Nielsen Company data published in mid-September: Fifty percent of iOS users have accessed the app within the last 30 days, compared with 45 percent of BlackBerry users and 32 percent of Windows Phone users. In addition, Facebook is the second most popular app among Android users (45 percent)--only Google Maps ranks higher (46 percent).
