Listen To The Story

Google's been making a lot of headlines this week between its new update to its maps and social media services, its introduction of a competitor to Spotify, and its developers' conference in San Francisco. At the same time, the search giant has been engaging in a war of words with Microsoft over the new Windows Phone. Google says Microsoft was not serving ads properly on its YouTube app, opening up the possibility that Windows Phone users will lose the app as soon as next week.

Microsoft representatives have responded to a cease and desist letter from Google. They say they'd be happy to work with the search engine giant to make sure they can deliver the ads.
