2015 Earnings: $12 million
The Beatles were a musical phenomenon whose influence is still felt (and heard) today -- an influence from which John Lennon’s estate still benefits in a big way. Lennon continually rakes in millions from a share of Beatles albums sales, including the latest reissue of their greatest hits in 1, which reentered the Top 10 of the Billboard 200 albums chart in 2015. Lennon also boasts his own incredibly successful solo catalog, and the Cirque du Soleil Last Vegas Beatles show Love! helps tide his estate over when the Beatles aren't ruling the charts.
