A Majority of U.S. Adults Now Use Social Media: Pew Study

Social media usage among American adults has ballooned in the past decade with about two-thirds now on social networking sites, Pew Research Center said on Thursday.

The 65 percent of adults in the United States using social media is up from 46 percent in 2010 and just 7 percent in 2005, the year Pew began tracking usage.

Since the early 2000s, social media sites on the Internet have surged in popularity, from Friendster and Myspace to Facebook and Twitter, among others.
