The Economist 28 April 2005
"This year the combined advertising revenues of Google and Yahoo! will rival the combined prime-time ad revenues of America's three big television networks, ABC, CBS and NBC, predicts Advertising Age. "
"Terry Semel, Yahoo!'s boss, believes there is a lot more growth to come as firms become even more familiar with online advertising. He happily points out that many big firms still allocate only 2-4% of their marketing budgets to the internet, although it represents about 15% of consumers' media consumption—and is growing. Many young people already spend more time online than they do watching TV."
