UK online advertising revenues hit £2.8bn in 2007

"In 2007, online revenues rose £797m like-for-like, to reach £2.8bn. The rise represented a slowdown from growth of 41% in 2006 and 66% in 2005 but it outstripped the IAB's forecasts of 35%. That prediction was already ahead of most other forecasts, said the trade group."
