However, Google declined to confirm the use of the iFrame player API by Microsoft, instead saying that a decision had not been made about which YouTube-related API or APIs would be called by the app.
The collaboration may put an end to the dispute between Microsoft and Google over YouTube, a brouhaha that goes back years. In March 2011, Brad Smith, Microsoft's general counsel, said Microsoft had filed a formal complaint with European antitrust regulators, and among several reasons, cited Google's refusal to put Windows Phone on par with rival mobile operating systems, including Android and Apple's iOS, in accessing YouTube.
The spat over YouTube was just a minor skirmish in the ongoing war between the two technology firms that has enveloped everything from search and office productivity applications to browsers and operating systems. Microsoft has been the aggressor in that war, said Gottheil two weeks ago, ticking off Redmond's continuing "Scroggled" attack ad campaigns and its pursuit of patent licensing fees from smartphone makers who rely on Android to power their devices.
"Microsoft has expressed its antagonism for far longer, but this is the first time where Google is fighting back in a public way," said Gottheil then of the YouTube dust-up.
