  The Wireless Telegraph and Signal Company became Marconi Company near the end of the 19th century. A Department of this Society (Marconiphone) produced domestic equipments from 1920 and was sold to the HMV in 1929. The HMV became part of Columbia Gramophone Company that acquired therefore the right to use the Marconiphone brand and the logo G.Marconi. The Gramophone Company became EMI from 1931 to 1956 and then became part of the THORN group. Therefore all the production between 1929 and 1979 has nothing to do with the Marconi Company. In 1979 the Marconi Company bought back the marks Marconiphone and G.Marconi.
