Summary: The service was marketed from 6 May 2008 and offers a satellite alternative to the Freeview service on digital terrestrial television, with a selection of channels available without subscription for users purchasing a receiver. The service also makes use of the additional capacity available on digital satellite broadcasting to offer a selection of high-definition programming from the BBC and ITV. Freesat should be using Youview, considering the backers in it, and the huge investment in Freeview taken by both parties. - appmarket.tv
