We have been using the Periscope app a little bit here at WGNA but apparently this video is Carrie Underwood's first attempt to use Periscope and it seemed to go pretty well!  She obviously didn't have any tutorial before she started and ended up not really having anything planned to say which was nice because her fans got to ask her questions and get her immediate feedback. My favorite part is when she says she is waiting all day for Sunday night. lol
