Digital Trends: Hulu is taking advantage of iOS 9’s new picture-in-picture functionality to let you watch TV shows while performing other tasks. The streamer is the first major video service to include the new feature, which is only available on the latest iPads, for its recent iOS 9 app update. For Hulu users with compatible iPads, the new feature will allow you to check email while catching up on “Top Chef” or “The Mindy Project.”
