British Technology Group established a company, Compeda Ltd, to exploit software developed and owned by the government; they took over the marketing and user support of PDMS, while the software continued to be developed by the CADCentre, with funding from Compeda.
1982 Compeda was the largest UK-owned firm in the fast expanding market of computer science.
1982 When the UK government decided to privatise (sell) anything that did not need to be government-owned, Compeda Ltd was sold to Prime Computer Inc. for a net negative sum of money (the government having prevented a sale to Computervision, said to have been at a higher price). Prime Computer decided that PDMS had no commercial value or future and returned the marketing rights for the product to CADCentre.
CADCentre was later privatised
2001 CADCentre changed its name to AVEVA.
