AC/DC

AC/DC's wealth story is fascinating because it's built on volume and longevity rather than flashy modern monetization. Their 1980 album 'Back in Black' alone has sold over 50 million copies worldwide, generating roughly $100 million in revenue over four decades. Unlike many bands who chase trends, AC/DC stuck to their formula and watched it compound—their catalog generates about $15 million annually just from streaming and radio play, with 'Thunderstruck' alone earning over $2 million per year.

The band's touring empire is where the real money flows. Their 2015-2016 Rock or Bust tour grossed $221 million, and they've consistently ranked among the top-grossing live acts for decades. What's remarkable is their ticket pricing strategy—they've historically kept prices relatively affordable compared to peers, focusing on volume and repeat customers. This approach has paid off massively, as they can sell out stadiums worldwide and have built an incredibly loyal fanbase that spans generations.

However, AC/DC's conservative approach has also cost them potential millions. They were notoriously late to embrace digital platforms, only joining Spotify in 2012, missing years of early streaming revenue. They've also been selective about endorsement deals and haven't capitalized on the celebrity culture boom like other rock stars. The band members split everything relatively evenly, which means no single member is extraordinarily wealthy, but all are comfortably set for life—a rare example of rock and roll fiscal responsibility.
