Jazz rode the 1990s surprisingly well. It was a decade in which the recorded-music market was flat compared to other media; and traditionally, jazz--which has a perennial single-digit market share--is an early casualty of the budget cuts and corporate take-overs that market slumps spawn. But that didn't happen in the 1990s. Moreover, jazz benefited from plunging CD production costs and e-commerce, which created a slew of independent labels and direct marketing conduits. And tens of millions of dollars from public and philanthropic sources, combined with increased corporate sponsorships of jazz festivals from coast to coast (a bid for the jazz audience's alleged upscale demographics), sustained a healthy live performance market throughout the decade.
