A very small fraction of Android users might notice a new button in their Twitter app. According to The Verge, the company has added a "go live" button that users can see when they compose tweets. It fires up Periscope when you tap it, so you can start broadcasting from within the application. But if you don't have the video streaming app yet, it takes you straight to Google Play. Twitter, which acquired Periscope in 2015, told The Verge that it's rolling out the "go live" button to a small number of users. It will eventually be available to everyone -- we're assuming even to iOS users -- though the spokesperson didn't mention when the feature will be officially released.
