• Movies: Only 0.9 percent of users use Facebook for Hollywood movies.

O&O’s findings are not too surprising. Premium video initiatives on Facebook are relatively new, whereas UK broadcasters own the online catch-up TV space and several aggregator brands already dominate online movies. Facebook is used far more for user-generated content, O&O found…

Indeed, YouTube (NSDQ: GOOG) recently said that 300 years, or 2.6 million hours, of YouTube video are watched on Facebook every day.

Ofcom reported in October that in the UK young adults use Facebook on mobile more than they do on PCs, and this shift to mobile meant there was less browsing time spent on the social network.
