Periscope videos to automatically play within Twitter for iPhone

Move puts Twitter ahead of Facebook but some see it as sign of failure to build dedicated Periscope community, and raises fears over data consumption

Starting today Twitter's Periscope live streaming videos will appear in users' feeds, right within the social network's main app on iPhones and iPads.

The move will see Twitter-owned Periscope video cards automatically playing within the Twitter iOS app, in a similar way to Twitter's Vines, pre-recorded video or gifs - which all currently download and play without requiring the user to interact with them.
