New York—Online ad revenue totaled more than $2.4 billion in the third quarter, up 35.3% from the year-earlier period, according to the Internet Ad Revenue Report, produced by PricewaterhouseCoopers for the Interactive Advertising Bureau.
The gain represented the eighth consecutive quarterly increase.
The report found that online ad revenue for the first three quarters of this year totaled slightly more than $7 billion, compared with a total of $7.3 billion reported for all of 2003.
The third-quarter ad revenue figure was estimated by surveying and aggregating data from the top 15 online ad sellers. The results were extrapolated to calculate the total estimated industry revenue figure.
The IAB also released a new standard for global online ad impression measurement, which is designed to simplify the buying and selling of online advertising.
