Report: Internet ad spending up 25 percent in 2007
Internet advertising sales are expected to have risen to a record $21.1 billion in 2007, up 25 percent from the previous year, according to a report released by the Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers.
Each quarter was a record, including $5.9 billion for the fourth quarter. That represented the most ever reported in a quarter and a 24 percent increase over the fourth quarter of 2006.
The report, which will be updated with actual full-year figures in May, was conducted by PricewaterhouseCoopers and sponsored by the IAB.
