In the past I've worked on a number of mobile projects for very large organizations (e.g., major sports organizations) that have restricted certain video streams based on the screen size of the device. In most of these cases, it was due to contracts that were made 5-10+ years ago that gave some company the exclusive rights to their video on various size screens (e.g., 'screens less than 5" diagonally'), or even TV/'Not TV'. Sometimes it was even split up between companies across 3 or 4 different ranges of screen sizes. In some cases, we had to build the apps to use Company A video streams on iPhones, and Company B streams on iPads. To make things worse (at least for the consumer), sometimes the app was allowed to AirPlay from the iPad but not from the iPhone, or even not at all, because of these contracts.
