Over 13,000 IVC800 series were sold worldwide from the late 1960s through to 1989. Prices (in 1970) for the 800 series ranged from US$5,000 for the basic 801 record/play machine through to US$10,000 for the 871 insert and assemble edit version. The 800 series, together with spares, accessories, service and support, gave rise to revenues in excess of two hundred million dollars during the 20 year lifetime of the range. IVC's other professional video products contributed a similar amount. The company was a substantial business in both the US and the UK with high tech headquarters at Sunnyvale in the California silicon valley, and at Reading England in the Thames Valley equivalent.
