When Microsoft purchased Skype it was pretty obvious that Messenger was probably going to either be merged, or disapear. This ancouncment from Microsoft spells then end of messenger.
We are retiring the existing Messenger service globally (except for mainland China where Messenger will continue to be available) and bringing the great features of Messenger and Skype together. Update to Skype and sign in using a Microsoft Account (same as your Messenger ID) and all your Messenger contacts will be at your fingertips. You’ll be able to instant message and video chat with them just like before, and also discover new ways of staying in touch with Skype on your mobile and tablet.
