Bing announced big news for them, that they took the AOL search partnership deal away from Google and will start powering AOL Search starting on January 1, 2016.
This is a 10 year deal, which is includes both organic search and paid search ads through Bing Ads.
This is small potatoes for Google, since AOL has less than one-percent mark share but with Bing's 20% share, every small amount makes a difference.
Microsoft said in their announcement:
Bing will now power search and search advertising across the AOL portfolio of sites. This 10-year agreement will enable AOL users to have access to world-class search powered by Bing across the company’s global portfolio of sites. Now with 20 percent organic market share in the U.S., Bing continues to grow organically as well as through key partnerships like the one with AOL. This deal with AOL is the latest to validate the quality of Bing results and the performance of the Bing Ads marketplace. Bing is also an integral part of popular first- and third-party devices and services.
With this, AOL is taking over Microsoft's display ad business, you can read more of the news over here.
