Facebook and Twitter have overtaken popular sites such as BBC iPlayer, ITV Player and Sky Sports.com.

Whilst probably not surprising, Experian Hitwise have made it official. At the start of 2011, Facebook consumed 12.46% of all internet activity, compared the entertainment sites which had 12.18%.

The figures are huge considering in 2008 social networking accounted for 8%.

In January 2011 alone, 2.4 billion visits were made to social networking sites. Facebook topped the charts whilst YouTube and Twitter came second and third.

Importantly, users don’t just use Facebook and then log off, in most cases, users then logged on to other social sites such as Twitter and foursquare.

Robin Goad, research director at the online intelligence firm, said businesses need to embrace the move toward social media- and fast!

‘Successful websites will be those that learn to harness the power of social networks, driving traffic to their own websites’.
