An international version of the iPlayer was launched on 28 July 2011 in eleven western European countries, after receiving the approval of the BBC Trust in November 2010. The international iPlayer takes the form of an iPad application which offers a limited amount of free content, supported by pre-roll ads and sponsorship, but its core business model is subscription (subscription costs approximately £5.00 per month). The global iPlayer app includes some features that are not in the UK version, including the ability to stream shows over 3G as well as Wi-Fi, and a downloading feature to store programmes on one's mobile device for offline viewing. At launch 1,500 hours of content was made available, of which 60% had been produced and commissioned by the BBC, while 30% had been commissioned by the BBC but produced by independents. The other 10% was entirely non-BBC content, including ITV's "Primeval", and Channel 4's "The Naked Chef" and "Misfits". Launches in Australia and Canada followed by the end of 2011 as part of what was intended to be a one-year pilot.
