The figures come from the Interactive Advertising Bureau and PricewaterhouseCoopers. They show that online adspend reached a record £151.6m in the first half of 2003 and that year-on-year growth was 85%.
The IAB is now predicting that online advertising for the year 2003 will top £300m for the first time. It now accounts for 2% of the market, compared with cinema's 1.1% and radio's 3.7% of total advertising expenditure.
The survey found that while banner advertising remained the most popular format, paid-for search listings now account for 36% of the market. Classified ads account for 12% and sponsorship for 6%.
Danny Meadows-Klue, chief executive of the IAB, said: "Marketers are investing more online every month because it works. Online is being used by mainstream marketers to support every aspect of the marketing mix, with a powerful track record now proven for those building brands and generating response."
