SAN FRANCISCO, Dec 16 — Twitter Inc yesterday said it would shut down live-streaming app Periscope, which it bought in 2015, due to declining usage over the past couple of years and high supporting costs.

The mobile app has been in "an unsustainable maintenance-mode state” for a while, Twitter said in a blog post.

Most of Periscope’s core capabilities have been integrated into Twitter and the company plans to remove it from app stores by March 2021.

Broadcasts that were shared to Twitter will stay on as replays and users will be able to download an archive of their Periscope broadcasts and data before the app is removed, the company said. — Reuters
