A company currently owns it in Luxembourg called Skype Technologies S.A.R.L, which since 2011 has been part of Microsoft. (From 2005 to 2011, Skype was owned by eBay.)
The Skype program works on computers with Microsoft Windows, macOS and Linux. It is available as a mobile app for different platforms, including iOS and Android. Using VoIP to make calls is very cheap to call another phone. It does not cost money to call another Skype user. Every Skype user has a unique name to which other users can find and talk.
