PC World is part of the DSG Retail Group. In 1993 The Group bought Vision Technology Group Ltd (VTA), which operated four PC World Superstores and a group of companies selling mail order PCs, peripherals, software and accessories to companies, educational institutions and private individuals.
VTG's PC World Superstores were based in Croydon, Lakeside Retail Park at West Thurrock, Brentford and Staples Corner, north London.
The Group sold VTG's mail order division and focused on the retail side of the business.
In 1996, The Group acquired DN Computer Services plc (DNCS), the computer reseller business, which became part of the PC World division. DNCS enabled PC World to establish an even stronger position in the £3 billion business-to-business market.
In 1998, The Group acquired Byte Computer Superstores Ltd with 16 retail outlets.
