Read this: A guide to the Sky v BT Sport Ofcom investigation and Competition Appeal Tribunal Decision

Summary: Equally important to the way in which sports content is made available to TV viewers are the various quotOff the pitchquot legal battles that BT Sport and Sky have been fighting, in particular following Ofcom's decision to impose quotMust offerquot obligations on Sky to make available its Sky Sports 1 and 2 channels to other broadcast platforms. Three years later, Ofcom decided that Sky should be forced to make available its core sports channels to competing broadcast platforms, a remedy which has become known as the quotWholesale Must Offerquot or quotWMOquot.3 Ofcom's decision was based on the perceived importance of those channels in enabling pay-TV operators to compete for subscribers with Sky and the fact that, absent regulatory intervention, Sky might not necessarily be incentivised to make them available to its competitors on reasonable commercial terms. - www.lawinsport.com
