If you’re thinking that Yahoo and Microsoft have a search deal, you remember correctly. They do, and they renewed that in April of this year. Our FAQ: The New Yahoo-Microsoft Deal, Explained story also had more background on that.
As part of the renewal, Yahoo agreed that Bing’s ads would appear on 51 percent of the desktop searches that Yahoo delivers. The other 49 percent could be “powered” by Yahoo’s own ad system or from any third party that Yahoo wanted to use.
