Bertelsmann Music Group is the end result of a number of mergers, primarily the 1985 merger of BMG and RCA. Those two companies have roots deep in the past, with Bertelsmann emerging around 1835 as a printer and publisher and the Radio Corporation of America incorporated in 1919 by General Electric. Other notable labels have been incorporated into the group, including Arista in 1979 and Zomba / Jive in the late 90s.
