The current music industry emerged around the middle of the 20th century, when records had supplanted sheet music as the largest player in the music business: in the commercial world, people began speaking of "the recording industry" as a loose synonym of "the music industry". Along with their numerous subsidiaries, a large majority of this market for recorded music is controlled by three major corporate labels: the French-owned Universal Music Group, the Japanese-owned Sony Music Entertainment, and the US-owned Warner Music Group. The largest portion of the live music market is controlled by Live Nation, the largest promoter and music venue owner. Live Nation is a former subsidiary of Clear Channel Communications, which is the largest owner of radio stations in the United States. Creative Artists Agency is a large a management and booking company.
