Grandslam Interactive

Grandslam Interactive Ltd. (formerly Grandslam Entertainments Ltd. and later Grandslam Video Ltd.) was a video games software house based in Britain. It was formed in late 1987 from a management buy-out of Argus Press Software by former Argus Managing Director, Stephen Hall and close friend David C. Dudman. Grandslam developed and published many games for home computers during the 1980s and 1990s. Originally based in central London, the offices were relocated to Croydon in 1990.
