Commercial and public television stations and cable outlets that devote much of their programming to news and public affairs have a built-in audience for debates. And don't write off local cable channels. About 75 percent of Americans now have access to cable, and surveys show that about 50 percent of cable subscribers watch community access channels on a regular basis. Such channels are eager for program material, and will be happy to show a debate not just once but several times. Radio is more fragmented than television, and does not hold an audience in the same way.
People tend to listen while driving or as background to some other activity.
Contacting Broadcasters Contact a variety of broadcasters as soon as you can tell them about the initial plans for your debate. Broadcasters will be more likely to carry your debate if they are part of the planning process, but they will also want assurances that you can get the major candidates to commit to participation. Your letter should be strong and persuasive, and include a brief outline of your debate plans. Play up the debate's importance as a public service and its appeal to an influential audience. Come prepared with your ideas, but be willing to consider suggestions from the pros.
