 The BBC and many of the independent TV companies installed the cameras in their studios during the rapid expansion of the UK colour services after 1967.However, by the time EMI had fulfilled its UK orders (towards the end of the decade), the boom in the US market had been missed and the European market had yet to fully develop or was already dominated by Philips cameras.In addition, rival companies were already bringing out new designs and EMI now found only a limited market for a camera with a 4-tube configuration.
