The Quantel Paintbox was a dedicated computer graphics workstation for composition of broadcast television video and graphics. Produced by the British production equipment manufacturer Quantel (which, via a series of mergers, is now part of Grass Valley), its design emphasized the studio workflow efficiency required for live news production. At a price of about US$250,000 (equivalent to $652,000 in 2021) per unit, they were used primarily by large TV networks such as NBC, while in the UK, Peter Claridge's company CAL Videographics was the first commercial company to purchase one. Following its initial launch in 1981, the Paintbox revolutionised the production of television graphics.
