Microsoft's Skype has finally shut down, concluding its 22-year tenure as the once-dominant internet calling and messaging service.

The decision to scrap Skype, announced in March, caps a remarkable 21-year run for a software that for many embodied the early values of the open internet: It was mostly free, had a user-friendly interface and made it easier for people to connect across the world. In its heyday, Skype had over 300 million users.

Microsoft is officially shutting down Skype today and urging users to migrate to Microsoft Teams as its replacement.
