Its initial business was pressing records in Canada for these companies.
Compo was one of only two Canadian record companies to survive the Great Depression.
RCA Victor Records of Canada—formerly Berliner Gramophone—was the other (it is currently the oldest Canadian label that forms part of Sony Music Entertainment in Canada).
American Decca bought Compo in 1951 with Berliner staying on as president until his death in 1966.
The company eventually evolved into Universal Music Canada.
