Rank Audio Visual was created in 1960, bringing together Rank's acquisitions in multimedia, including Bell & Howell (acquired with Gaumont British in 1941), Andrew Smith Harkness Ltd (1952) and Wharfedale Ltd (1958). Subsequent acquisitions included Strand Electric Holdings (1968) and H.J. Leak & Co. (1969). In the mid and late 1970s, Rank Audio Visual made a 3-in-1 stereo music centre, as well as TV sets in conjunction with NEC of Japan. The production of the "classic" Rank TV ran in the mid to late 70s, some interim models appeared and the "modern" Rank TV appeared in the early 1980s. The NEC badge did not appear in the PAL/220/240 volt countries until the mid-1980s.
