Periscope

Periscope streams now play automatically on Twitter's mobile app

Footage being broadcast through the app will be treated like any other video on the microblogging service, saving users a click or a tap.

Clicking through allows users to watch, like or comment on the full stream without logging into their Periscope account. In fact, you don't even need a Periscope account at all.

The feature is now live on Twitter's iOS app, and is coming to Android and the web in the near future.
