A new report from Nielsen notes that Americans 18-34 years of age are less reliant upon social media than some older consumers. “Adults 35 to 49 were found to spend an average of 6 hours 58 minutes a week on social media, compared with 6 hours 19 minutes a week for their younger counterparts,” reports The New York Times. “More predictably, adults 50 and over spent significantly less time on social media, with an average of 4 hours 9 minutes a week on the networks.” Not surprisingly, the report stressed how important smartphones have become to people of all ages. The most popular mobile platforms, in order: Facebook, Instagram, Twitter, Pinterest, LinkedIn, Snapchat.
