Skype: May 10, 2011
In its largest acquisition, Microsoft bought popular VoIP services company Skype for $8.5 billion. With the acquisition came scrutiny that Microsoft had paid too much for a company that reported a revenue loss the previous year. In a press release, Microsoft said, "Skype will support Microsoft devices like Xbox and Kinect, Windows Phone and a wide array of Windows devices, and Microsoft will connect Skype users with Lync, Outlook, Xbox Live and other communities." Since the acquisition, Microsoft has not released revenue lost or gained by Skype, but a February 2013 Bloomberg report said the Skype unit "including Lync software for corporate instant messaging and Internet calling is approaching $2 billion in annual sales."
