Facebook Leads Social Pack in US, Twitter Sputters: Study
 

Facebook remains the dominant social network for US Internet users, while Twitter has failed to keep apace with rivals like Instagram and Pinterest, a study showed Wednesday. The Pew Research Center report found 72 percent of Americans who are online currently use Facebook, a modest uptick of one percentage point from a year ago and five points higher than in 2012. Because the vast majority of Americans use the Internet, the figures suggest 62 percent of all US adults are on Facebook, according to Pew.
