Warner Music Group

The “Big Four” record companies, already responsible for more than 80% of album sales on the planet, may be on the verge of becoming the “Big Three”. On May 6, Warner Music Group was sold to Ukrainian-American tycoon Leonard Blavatnik. Warner is the world's third largest record company. Blavatnik ― the world's 80th richest man ― is also rumored to have his sights set on number four EMI. If that sale comes to pass, it will create the largest music label in history.
