Domark Group Ltd.
Formed in about 1990 and located in London (United Kingdom), Domark Group Ltd. was the main corporate entity for the entire Domark conglomerate of companies including Domark Software Ltd. (UK) and Domark Software Inc. (USA). This company was the owner of all copyrights, licenses, and trademarks acquired and created by Domark collectively.
This name is most commonly credited with "Software, Instructions, Artwork and Packaging" on game boxes and in credits. It is believed that production of marketing materials, promotions, artwork and printing was handled by this company, leaving the creation of the actual products to the lower divisions.
This is the entity named in the legalities of the October 1995 Eidos acquisition of Domark.
