Search on Google for the word "Olympics." Google very clearly shows that the advertisements on the right side of the page are "sponsored links." Google also shows that the Chevrolet ad at the top of the page is a sponsored link.
But a big chunk of the page offers links to video, event schedules, the medal count and a map of Turin. And that chunk of page is offered "in collaboration with NBC Olympics." The section also gives the Web address of NBC's Olympics page.
Does this count as a sponsored link and, if so, shouldn't Google state that fact?
Here's what happens when you perform that search on MSN Search and Yahoo Search.
