Radio is an intrusive advertising medium needed to support print, which is not. It also provides the frequency critical to the success of any advertising. Radio is a great way to direct people to your website. Jazz listeners are loyal. This loyalty extends to sponsors also.
Jazz is music that involves the listeners.
This extends to the advertisement messages also. You get the prestige and satisfaction of helping to bring great music to people. It enables you to be associated with innovation in a world of conformity. The shows are only on commercial stations, not public stations, where the content of the advertising messages is regulated and curtailed. Neither program is ever aired between Midnight and 7am.
