title offered "a tired question and answer format in what should be an innovative new medium", a response to this particular review attempted to address such criticisms by noting the limitations of the interaction method employed by the Domesday system, the tightly coupled sound and video capabilities of the medium, and the need to deliver and improve the software without involving the "expensive and complex LV-ROM mastering process". The response also questioned the future of the LV-ROM format, in contrast to Laservision and CD-ROM, also indicating that CD-I would remove various restrictions experienced with the laserdisc medium. The BBC's Countryside disc provided various census and agricultural datasets and was sponsored by a broad consortium of public and private sector organisations. The BBC's Volcanoes disc, produced in association with Oxford University Press, featured volcanic eruption footage and animated computer graphics sequences by award-winning animator, Rod Lord, together with hypertext features. The Volcanoes disc (priced at £194.35) employed "new AIV features like hypertext" and had graphical content that was created on Archimedes computers. Shell Education Services offered an "interactive video project pack" intended for educational use in various subjects based on "a system developed by Shell UK to provide route maps in filling stations". Epic Industrial Communications offered a "complete course in solid state electronics" for the AIV system, priced at £2300 plus VAT. Support software was also made for the AIV platform such as the Domesday Display application suite which allowed users to extract data and pictures from the laserdiscs and to present them in the form of a slideshow. The Domesday Presenter application focused on Domesday and AIV system laserdiscs, whereas the Domesday Captions application allowed video frames to be selected from AIV system laserdiscs or any other CAV (constant angular velocity) laserdisc, with the user adding their own captions. Although this particular interactive video implementation had progressed away from previous "cumbersome and boring" solutions relying on the navigation of sequential-access video tape, tape-based solutions persisted as competitors. For example, the tape-based VP170 Video Presenter package from Interactive Media Resources (whose system processor was packaged similarly to an Acorn second processor) and the Companion system from Bevan Technology which could control VHS-based tape and Philips LaserVision players, both apparently offered support for integration with applications using the Microtext language. Ivan Berg Software (a one-time partner with Acornsoft on various titles) offered the Take Five system on Betamax format video tape
