Microsoft announced that downloads of its Skype client on mobile devices have now reached the 1 billion milestone worldwide.
Microsoft marked the occasion with a blog post, stating:
That's a huge milestone and we wanted to say a huge thank you to everyone that has downloaded Skype on their mobile. Wherever you are, from the US and Russia, to the Cocos Islands and Pitcairn (guess how many people use Skype in Pitcairn #SkypeTrivia), you've all helped Skype grow from just a few users in Tallinn, Estonia, to hundreds of millions in every corner of the earth.
Skype launched its first mobile client for the iPhone in May 2010 and followed that with the Android version in November of that same year. The first public beta of a Skype app for Windows Phone 7 was released in February 2012, several months after Microsoft acquired Skype in 2011. New versions were released for Windows Phone 8 and 8.1, along with Windows 8 and 8.1 for the PC.
Microsoft at first decided to integrate Skype features in its Messaging, Phone and Video apps in Windows 10 and Windows 10 Mobile, but recently it announced it was altering those plans and would launch a universal Skype app for both platforms. A preview version of Skype for Windows 10 is currently available for members of the Windows Insider program, with the Windows 10 Mobile version due in the near future.
