The Federal Communications Commission requires that applicants for new broadcast licenses and for changes in existing licenses must demonstrate that they have attempted to ascertain the problems, needs, and interests of the residents of their community of license and of other areas they undertake to serve, and must propose broadcast matter (defined as programs and announcements) to meet these needs. To clarify this requirement and to provide additional guidelines, a tentative "primer" in the form of questions and answers was prepared. This primer was submitted to the Federal Communications Bar Association (FCBA) for comment. The resulting version of the primer, along with the comments of members of the FCBA and the replies of the FCC, is presented here. The names of the 61 parties filing comments are appended. (JY)
