PolyGram 's acquisition of Decca was full circle .
GPG needed to move into the US and UK markets , and did so by a process of both formation and acquisition : Polydor Records established its American operations in 1969 , Mercury Record Productions ( US ) was acquired in 1972 from sister company North American Philips Corp. , RSO ( UK ) in 1967 , MGM Records and Verve ( US ) in 1972 , Casablanca ( US ) in 1977 , Pickwick in 1978 , and Decca ( UK ) in 1980 ( the latter acquisition basically brought PolyGram full circle , see the HDD section above ) .
