Microsoft created MSN Messenger in 1999 to compete with AOL's highly popular instant messaging service AIM. MSN Messenger was re-named to Windows Live Messenger in 2005 as part of Microsoft's push to re-brand many MSN services and programs with the Windows Live name.
In May 2011, Microsoft purchased Skype, a free instant messaging, voice call and video call service, for $8.5 billion. Users who paid for Skype Credit could also use Skype to make international phone calls from their computers. In December 2012, Microsoft announced that it would merge Windows Live Messenger and Skype in early 2013, allowing users to log into Skype using their Microsoft accounts and access their old contacts. By April 2013, Windows Live Messenger had been completely phased out for English users.
