Given that Twitter owns Periscope, we suppose the integration makes sense. However we should note that the button does not actually begin the recording, but rather it will launch the Periscope app and users can begin their broadcast then. If users do not have the Periscope app installed, then they will be redirected to their respective app stores to install it.
Essentially what this is is a shortcut. According to Twitter who gave a statement to The Verge, it seems that the feature hasn’t rolled out to all users yet, but they have begun the process of doing so. “We’re rolling out a ‘Go Live’ button in Twitter to a small percentage of users. Over time, all users will have the ability to start a Periscope broadcast from Twitter.”
No word on when this will be rolled out to all Twitter users, but in the meantime if you have the Twitter app installed you can keep an eye out for it.
