Internet advertising in the UK is now breathing down the neck of radio in terms of annual adspend, reports the Interactive Advertising Bureau, citing a study conducted by PriceWaterhouseCoopers.

Online ad budgets leapt 76% to £266.8 million ($478.5m; €385.33m) during the first half of 2004, with the likes of BMW, BT and Audi blazing the trail.

On the basis of the current data, the IAB, hypes the internet as the fastest growing advertising medium in history – a bold (and almost certainly inaccurate) claim given the spectacular rise of TV in the USA in the 1950s.

The IAB's UK chief executive, Danny Meadows-Klue, is confident total internet adspend during 2004 will comfortably top £500 million.
