For the few who are yet to use it, Periscope is a live streaming smartphone app which lets you "broadcast live video to the world." It really isn't the world you'll be broadcasting to though. It's only your followers who'll see your video. When you go "live" your followers will get a notification and if they are interested they'll watch the video. When the broadcast is over the video can be replayed then afterwards removed from the App. If you've got a gift of the gab, this can be a great way to promote your business. Just curious, have any of you used Periscope to promote your business? Any tips you can offer those who haven't?
