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

Microsoft decided to shut down Skype to focus its resources on developing its Microsoft Teams app, which includes the services that Skype provided plus more.

Contrary to its quick growth, Skype’s decline was long in the making. Two years after launching, Skype had about 50 million registered users, which led to the subsequent acquisition by Ebay for $2.6 billion that same year. At its peak, it would hit an all-time high of over 300 million users.
