1920s-1960s
In the United Kingdom and the Commonwealth, the Gramophone Company continued to use the "Zonophone" label until 1931. When the company merged with the Columbia Graphophone Company to form Electrical and Musical Industries, Ltd. (EMI), the lower-priced labels of the two firms were merged also as Regal Zonophone. Post WWII, Regal Zonophone was largely dormant in Britain until 1964, when the label was revived with a few beat group offerings but became primarily known for hosting the Salvation Army-affiliated band The Joystrings, who had a brace of chart placings and released several 45s, EPs and LPs through the end of the 1960s. The Joystrings appearance on the label hearkened back to the 1930s and 1940s when Regal Zonophone regularly released Salvation Army brass band recordings. Regal Zonophone was also widely used as a catchall EMI label in foreign territories, and often in regions or nations where the main EMI Columbia and HMV logos and trademarks were disputed/held by competitors.
In Anglophone West Africa (primarily today's Ghana and Nigeria) Zonophone was used as a label to record and produce Sakara, Juju and Apala music on 78rpm discs from 1928 to the early 1950s.
