A WebmasterWorld thread is reporting that Bing is advertising their search engine on Intellitxt. Intellitxt are those ads you see inline articles, where you mouse over a word and an annoying ad pops up. I personally find those ads to be incredibly annoying, intrusive and invasive. But many publishers use them and according to the WebmasterWorld post, Bing is using it to advertise their search engine.
The thread said:
At a very popular UK website I noticed an Intellitxt ad featuring a Bing Search of the phrase in the ad. Good idea by Bing.
I do not have a screen shot, but if you see one, please send it my way.
