From Business Insider:
At Business Insider’s IGNITION event last week, Business Insider CEO Henry Blodget detailed the future of the digital landscape, pointing out some important trends. For example, more than a quarter of all internet traffic now comes from smartphones and tablets — and two big internet properties are responsible for a huge amount of that traffic.
Based on data from a Sandvine report charted for us by BI Intelligence, Facebook and YouTube accounted for nearly 40% of all mobile web traffic in North America in September. Facebook accounted for 19% of that aggregate mobile traffic, YouTube was close behind with 18%, and the third largest share belonged to “general web traffic” through web browsers, at 11%. As BI Intelligence’s Mark Hoelzel points out, ads make up a big percentage of Facebook’s and YouTube’s mobile traffic, since autoplay video ads increase the mobile data demands on those social networks.
