YouTube, Facebook Account for Nearly a Third of Mobile Traffic

Facebook and YouTube are now dominating mobile traffic shares in early 2014, as more people shift to a mobile device to upload photos to social networks and watch cat videos.

Facebook and YouTube now account for 32% of data sent to and from mobile devices, according to a report by Sandvine. Individually, Facebook's share was 26.9% for upstream traffic and had a 14% share for downstream traffic during peak periods in North America through the beginning of this year, while YouTube only had 3.7% share for upstream traffic, but a 17.6% share for downstream.
