Data Points: Social System

Facebook is still the biggest social network, but its growth has spawned many smaller options

Social media has gone global. Facebook, the most widely used network, is now available in more than 70 languages, with three-fourths of its 800 million active users living outside the U.S. But usage varies widely by region, according to a report on global social media adoption by Forrester Research. U.S. adults have a longer history with online networking, but they tend to use it in passive ways, engaging in activities like creating social network profiles, listening to podcasts and reading others' content. Those in emerging markets, meanwhile, are more likely to actively participate in it by posting status updates, contributing to blogs and uploading content they created.
