Electric and Musical Industries Ltd (EMI) was formed in 1931 to acquire the ownership of the Gramophone Company Limited (sometimes known as HMV after the company's His Master's Voice records) and the Columbia Graphophone Company Limited. The research groups of the two companies were merged. Previously HMV (in which RCA had a financial interest) had demonstrated in January 1931 a mechanical multi-zone television system, operating on 150 lines per picture, based on the use of cine film as the source of the televised images. Following the merger, EMI's directors agreed that HMV's television development effort should continue to be an item of the new company's R&D programme. One of the first questions that had to be tackled was whether this work should proceed on mechanical or electronic lines. Mechanical scanners had the advantage that they had been made successfully, whereas electronic scanners were still in the development phase. On the other hand, electronic scanning had many potential advantages for high-definition television.
