Blue and Machine Effects will retain their brands but Prime Focus London plc will replace VTR plc as the holding company name. Dormant companies Clear, The Hive, Clipstream and The Machine Room will be liquidated.
The company said the move will allow financial performance to be reported to shareholders by activity type.
Design agency Ammunition has been appointed to create the brands, which will be launched within three months. The announcement was made alongside the unveiling of the group's end-of-year financial results.
Pre-tax profits for the year ending 31 March 2008 were£472,538, compared with£646,422 for the seven months to March 2007.
This takes into account an exceptional charge of£604,461 paid to former managing director John Banks in settlement of proceedings for alleged breach of contract.
Turnover for the year was£18m, with sales remaining flat. However, the company has reduced its gross margins and has taken on more freelancers for specific projects.
It has also increased its operating profit by terminating the leases on two Soho buildings.
