Answer:
Michael Jackson bought the Beatles catalog when it went up for auction after he was advised by his friend Paul McCartney (one of the Beatles) to invest his money by buying into the music publishing business. McCartney hadn't wanted to spend the money to buy the catalog himself, but was later uphappy with Jackson both for buying it and for licensing the Beatles songs to be played in commercials. Jacksons purchase of the Beatles catalog marked the end of his friendship with McCartney but it remained a valuable asset to him for the rest of his life.
