According to Forrester Research Inc., households now spend at least 30% of their media time online, while the Internet has just 5% of total ad spending.
Last year U.S. advertising spending was an estimated $300 billion to $400 billion.
Just $10 billion of that was spent online, even less than for ads in the Yellow Pages.
Advertising Bureau and PricewaterhouseCoopers, online ad revenue grew 34% in the latest quarter, with total 2005 revenue on track to grow by 25%, to at least $12 billion; newspaper ad revenue, by contrast, is slated to grow less than 3% this year.
