I worry more about the marketing that's taken hold since the 70s. The Jazz era, the Swing era, those were huge. Entire decades were named for music. In the 1940s - after World War II - changes in taxation, ballrooms closing, people moving to the suburbs, and the onset of target marketing and the confusion of commerce with art caused some things to happen as a result that have taken us away from jazz and what jazz offers us.
One of the pleasant duties of America's most famous announcers during the relatively short swing era of the big bands was to host late-night remotes from some of the most famous ballrooms throughout the country.
