Following recent reports, Periscope announced today that it will end operations as a standalone app by March 2021. The Twitter -owned company referred to its current operations as “unsustainable” in an open letter posted today. It also cited a decline in usage in recent years as a driving factor.

“Leaving it in its current state isn’t doing right by the current and former Periscope community or by Twitter,” the company noted.
