Negotiations of the definitive agreement under which Microsoft would acquire Skype, an Internet communications company, for $8.5 billion were led by investor group Silver Lake and the transaction was originally announced on May 10, 2011. Boards of directors of both Microsoft and Skype previously approved the acquisition.
Microsoft and Skype will remain focused on their shared goal of connecting all people across all devices and accelerating both companies’ efforts to transform real-time communications for consumers and enterprise customers. The completion of the acquisition also marks the official introduction of Skype as a new business division within Microsoft.
It seems that probably Windows Live messenger would be merged with Skype. Thus a single unified application may be created.
