While the network did pass the 1 billion monthly active user threshold globally in 2012, Facebook also lost 1.4 million U.S. monthly active users late last year, a small but symbolic decline. Nor was it the only network experiencing a slowdown.
After years of double-digit expansion, social media use in the U.S. leveled off markedly last year. American social media users grew an estimated 6.8% in 2012, a far cry from 30 percent growth rates just a few years ago. With so many of the country’s 221 million netizens already logging into social networks, growth is forecast to slow to a trickle in the years ahead.
