RCA Records is an American record label owned by Sony Music Entertainment, a subsidiary of Sony Corporation of America. It is one of Sony Music's four flagship labels, alongside RCA's former long-time rival Columbia Records; also Arista Records, and Epic Records. The label has released multiple genres of music, including pop, classical, rock, hip hop, afrobeat, electronic, R&B, blues, jazz, and country. Its name is derived from the initials of its defunct parent company, the Radio Corporation of America (RCA). It was fully acquired by Bertelsmann in 1986, making it a part of Bertelsmann Music Group (BMG). RCA Records became a part of Sony BMG Music Entertainment after Sony and BMG merged in 2004; it was acquired by the latter in 2008, after the dissolution of Sony BMG and the restructuring of Sony Music. It is the second-oldest record label in American history, after sister label Columbia Records.
