The moves mean Microsoft will focus on its growing search advertising business based on its Bing search engine, and displaying maps on its Windows devices rather than generating the maps themselves.
               
Microsoft, which employs hundreds of people in its display ad business around the world, said those employees would be offered the chance to transfer to AOL and that it was not making any layoffs.
               
The world's largest software company no longer breaks out results for its online operations, chiefly its MSN web portal and Bing, but they have  lost more than $10 billion over the past five years. Chief Executive Satya Nadella has said Bing will turn a profit next fiscal year.
               
"Today's news is evidence of Microsoft's increased focus on our strengths: in this case, search and search advertising and building great content and consumer services," said Microsoft in a statement.
               
Under a 10-year deal struck with AOL, now a unit of Verizon Communications Inc, AOL will sell display ads on MSN, Outlook.com, Xbox, Skype and in some apps in major countries. As part of the deal, Bing will become the search engine behind web searches on AOL starting next year.
               
Microsoft also struck a multi-year extension to its existing deal with AppNexus, which provides the tech platform for buyers to purchase online ads.
               
Microsoft and Uber did not disclose financial terms of their deal, under which Uber will take over the part of Microsoft's  mapping unit that works on imagery acquisition and map data processing. Uber will offer jobs to the 100 or so Microsoft employees working in that area, according to a source familiar with the deal.
               
Fast-growing Uber, which is shaking up established taxi services worldwide, already uses a combination of map services from Google Inc, Apple Inc and China's Baidu and the source said it will continue to do so.
