Periscrope is Twitter's app for broadcasting live streams. Something's happening. You pull out your phone, you turn on the camera, and you show the world what's going on. Or at least the people who come across your account.

Since launch, the app has only supported vertical videos. But enough people have scoffed at this idea that the team is now introducing the option to turn your phone sideways. Landscape recording is making its way into the latest Android and iOS versions of the app.

Other additions include showing a list of mutual followers to pick from when you start a private video stream. This is what you do when you want to share something with your friends but not their parents and co-workers.
