Freesat
Freesat launched on 6 May 2008. It provides a subscription-free alternative to Sky and includes support for HD with a selection of HD channels available via a Freesat HD box.
Freesat is a not-for-profit company formed by the BBC and ITV, marketing itself as being completely free from subscription charges or contracts, although viewers of course are still obliged to pay the television licence, and must purchase a suitable satellite receiver and have a satellite dish installed (if they do not already have one) to receive the service. Freesat receivers are available in both standard definition and high definition versions. HD channels are available only when the satellite receiver is capable of supporting it.
