On Friday, Microsoft announced that the 21-year-old calling and messaging service will shut down May 5. The software company is encouraging Skype users to migrate to its free Teams app.

Skype won attention in the 2000s for giving people a way to talk without paying the phone company, but stumbled in the mobile era and didn't enjoy a major resurgence during the pandemic. Some people have forgotten that it's still available, given the many other options for chatting and calling.
