"We’d expect to see a difference in usage patterns between fixed and mobile Internet access, but the dominance of social gaming shown in these browsing figures is particularly surprising. It shows that, for many, keeping up to date with friends or regular gameplay on the move is now more important than accessing their emails via Hotmail or keeping up to date with the news.

The volumes of data we’re looking at show the importance of Mobile Broadband as an internet access channel – with nearly seven terabytes of Facebook browsing data being generated in just one week – and that doesn’t count the up and download volume."
