Grandstand (also known as Grandstand Leisure Products) is a video game console and electronic game manufacturer and distributor. It was based in the United Kingdom and New Zealand and was active in the 1970s and 1980s. Overview The company initially behind the Grandstand label was Adam Imports Ltd., (from 1980 Adam Leisure Group Ltd. and by 1983 Adam Leisure Group PLC) founded in 1973 by Chris Rycroft and Les Kenyon of Harrogate, UK. The company initially started as a mail order company and was the single largest supplier of calculators in the UK by 1974. By August 1978, George Bassett had acquired a 75% holding in the capital of Adam Imports for £750,000 cash, plus 60p in the pound of profits before tax in excess of £500,000 for year to December 31, 1978. Adam Imports was re-acquired from George Bassett by Chris Rycroft in 1980. It chiefly imported electronic products from other manufacturers such as VTech, Epoch, Tomy & Entex, selling them in the UK re-branded under the Grandstand name. Some imported products' names were changed for the UK market. For example, the Tomy tabletop electronic game sold in the US as Pac Man (and in Japan as Puck Man) was released by Grandstand in the UK re-badged as Munchman. Products Grandstand released numerous products over the years of which some are listed below. There were large numbers of similar variations, alternative names and model numbers typically referring to multiple evolutionary versions of the various game consoles and electronic games. Particularly, this is found with the Pong type game consoles as the semiconductor technology rapidly progressed during the period that the Grandstand brand was active.

These consoles, belonging to the PC-50x Family, were still essentially Pong type affairs, but had a limited selection of cartridges available, each housing a different General Instruments processor chip AY-3-8xxx. This arrangement allowed for some variation in gameplay including the implementation of simple racing games featuring Pong-era graphics. However, these systems lack the flexibility found in later ROM cartridge based consoles, and there were never more than a few such processor-based cartridges released.
