Satellite broadcaster BSkyB's Sky Box Office pay-per-view movie service and UK broadcaster Channel 4's subscription service FilmFour are going digital.

Sky Box Office and the FilmFour service will move exclusively to Sky's digital satellite platform in April. In a statement, the companies cited 'the rapid rate of digital take-up by former analogue subscribers' as the reason for the move. The companies added that most Sky Box Office customers and FilmFour satellite subscribers had already made the transition to digital.

Sky Box Office events, including sports and music, will continue to be available on analogue.

Two other channels, Granada Breeze and technology channel [.tv], will also move to digital in April. Sky aims to transfer all of its analogue satellite subscribers across to digital by the end of 2002.
