Microsoft told Mashable that its Bing search engine will be the default on the Amazon Kindle Fire HD‘s web browser. Amazon also confirmed it. The deal between the two companies came together recently. Adam Sohn, general manager of communications and influencer marketing at Bing, said the “last bits” of the deal were finalized only today.

The site Ubergizmo first reported that Bing was the default browser on the Kindle Fire HD.  Amazon is Microsoft’s second major partner in the mobile arena. The first was RIM — Microsoft CEO Steve Ballmer paid a visit to BlackBerry World in spring 2011 to announce that Bing would power search and maps on BlackBerry phones going forward.
