The largest IVC subsidiary company was the British, Reading-based, IVC UK Ltd which not only sold and serviced the IVC800 series (all with a “1” suffix in Europe, eg. 801, 871 etc.) but also designed and produced a range of complementary Digital Time Base Corrctors, Dual Imaging Effects Units, and Zoom Machines. IVC UK Ltd became the most profitable part of the IVC operation and was subsequently purchased by Carlton Communications plc in 1982 giving Carlton an entry into the TV equipment business. IVC UK Ltd went on to outlive its original Californian parent and generated major profits for Carlton.
