Sony Music [SEP] Introduction
In 2004, Sony and Bertelsmann established a 50-50 joint venture known as Sony BMG, which transferred the businesses of Sony Music and Bertelsmann Music Group into one entity. However, in 2008, Sony acquired Bertelsmann's stake, and the company reverted to the Sony Music name shortly after; the buyout allowed Sony to acquire all of BMG's labels, and led to the dissolution of BMG, which instead relaunched as BMG Rights Management. As of 2020, Sony Music Entertainment is the largest of the "Big Three" record companies, followed by Universal Music Group and Warner Music Group. Its music publishing division Sony/ATV is the largest music publisher in the world.
