The Communications Act of 1934 requires broadcasters to operate their stations "in the public interest, convenience, or necessity." But because broadcasters seek to make a profit and because the Federal Communications Commission (FCC) cannot adequately monitor the thousands of radio and television stations, many stations do not live up to that requirement or to more specific FCC policies. Therefore, it is up to the public to insure that broadcasters are serving the needs of the communities in which they operate. The results of a case against WLBT and WJTV in Jackson, Mississippi, and the effects of an agreement made with KTAL-TV in Texarkana, Texas, illustrate ways that community groups have been able to affect local broadcasting practices. A checklist of questions is provided to help citizens evaluate the broadcasts of their local stations. It suggests ways of helping to keep stations aware of community needs and problems. Also included is a list of national organizations which can help citizen groups make radio and television stations responsive to their communities. (JK)
