Social networking on mobile devices is going mainstream. Some 82 million U.S. mobile users, or 25.9% of all Americans, will access a social networking site on their phone at least monthly this year, according to a new estimate by eMarketer. Not surprisingly, most of that activity will happen on Facebook. Nearly 70 million people, or 85.4% of those social networking on phones, will visit Facebook each month in 2012. That share will climb to 87.4% by 2014.
Virtually all (95.5%) users will be checking social sites on a smartphone, and smartphone users are about twice as likely as overall mobile phone users to do so this year. In two years, eMarketer predicts almost half (46.3%) of the U.S. mobile population will be social networking on phones. Separate data from comScore showed 37% of U.S. mobile users accessed a social networking site or blog in June.
