social networks such as Facebook account for nearly half of the time that users spend online via handsets.
Web surfing social sites is an idle application. You load the page and then read. You type and upload. Then read some more. HTML pages constitute very little data and while you are reading you aren't generating any throughput at all.
Streaming video meanwhile is a bandwidth hogging consistency for the entire duration of viewing.
From what I have seen here in the US vs the test data from the UK, many users are frequently uploading video and photos from their phones. That traffic is a big deal on mobile networks. So, it isn't all just text typing and reading text pages now, there is a lot of uploading and downloading of videos and photos as well.
