Celebrating Bing Ads Special Day
"On September 10, 2012, adCenter was renamed to Bing Ads, and the Search Alliance was renamed the Yahoo! Bing Network."
If at this point, you still do not have a basic knowledge of what Bing Ads is, then I'll have to simply say that Bing Ads is the kind of Ads network that makes use of Pay Per Click advertising and Search Engine Marketing.
Bing Ads are featured on Bing Search Engine, Yahoo Search Engine and AOL.
