Coming soon on Frontline, on PBS:
The Way the Music Died
The modern music scene was created in 1969, at Woodstock. Half a million fans, dozens of artists, and the politics of the times came together as a big bang moment that eventually would generate billions of dollars. But over the last twenty years, MTV, compact discs, corporate consolidation, Internet piracy, and greed have contributed to a perfect storm for the recording industry. FRONTLINE examines how the business that has provided the soundtrack of the lives of a generation is on the verge of collapse.
Incidentally, if I remember right, the global revenue of the music industry is only about as much as the revenue of a middling insurance company. I'd bet that the porn industry is whole orders of magnitude bigger.
