On Christmas Day 2007 Facebook reached a peak in traffic that wasn’t surpassed until July 2008. Traffic reached a new high on Christmas Day 2008, when Britain’s most popular social networking site accounted for 1 in every 22 UK Internet visits. With a market share of 4.65% Facebook’s traffic was up 69% on Christmas Day 2007, and it was the second most visited website after Google UK (8.63%).
Hitwise Intelligence UK: Social Xmas: Facebook’s busiest day ever, YouTube overtakes Hotmail, Social networks = 10% of UK Internet traffic While I’m sure this is supposed to predict something about Facebook’s 2009 growth, I prefer to think of it as the death of the holiday card/letter…at least in the UK.
