Advertising revenues of Google + Yahoo > TV ads
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. Both Google and Yahoo! make most of their money from advertising. Auctioning keyword search-terms, which deliver, along with their own search results, sponsored links to advertisers' websites, has proved to be very lucrative. Advertisers like these links because, unlike with TV ads, they pay only for directly measurable results. They are charged when someone clicks through to their own website.
