Periscope is shutting down in March of 2021
Twitter has announced that its Periscope live streaming service is shutting down by March 31st, 2021.
In the post announcing the decision to discontinue Periscope, the development team explained that Periscope has been "in an unsustainable maintenance-mode state, and has been for a while." This, along with declining use and increased costs year over year, were the main reasons for the discontinuation. According to the post, this decision likely would have been made earlier in the year if the novel coronavirus pandemic hadn't rearranged priorities.
Periscope will be removed from the App Store and Google Play Store in March of 2021. Live broadcasting functionality will continue on in Twitter, though notably without the community features that Periscope has included since its inception. The ability to create an account for the service has been disabled as of December 15th, 2020.
According to the frequently asked questions page put up on the official Twitter support site, you will be able to request your Periscope data and download your broadcasts, with more info on how to do so coming "shortly."
