Internet advertising remained the fastest-growing advertising medium in 2007 and Key Note predicts it will increase 31.4% in the UK in 2008.

"Consumers will continue to filter not only general content but also advertising content, so that advertisers will have to take care not to cause the consumer any annoyance."
