CDS Software was an independent publisher and developer of computer game software founded by Giles Hunter, an entrepreneur and former manager of the local WH Smith newsagent store. In 1988 CDS Software, under the CDS group of companies changed its name to Nimrod Holdings Ltd. Publishing continued under the CDS Software Label until the early 1990's. The company name eventually changed to Guildhall Leisure Services and from 2002 to the present day it is known as iDigicon Ltd. The company was also known as CDS Micro Systems for its earlier titles, but the same 'three-leaf clover' CDS logo was used on the box art.
