The BBC Master-based system used to deliver the Domesday Project content, known as the Domesday Advanced Interactive Video (AIV) System, was also intended as a platform to support other interactive video applications, integrating with programming languages such as BASIC and Logo via the operating system. Opportunities were perceived for the introduction of the technology beyond the education sector and into various areas of the public and private sectors, estimating "300,000 potential business customers". Acorn set up a subsidiary, Acorn Video, offering the platform under the name Master Video with a choice of Philips or Pioneer laserdisc player for £3220, or £3750 for a more compact version. (This ostensibly followed on from earlier products: the Acorn Interactive System, based on the BBC Micro and Pioneer or Philips laserdisc player, which only supported unidirectional control of a laserdisc player via a serial link, and the Viewpoint Interactive Video Workstation.)
