１２０、The following appeared in a memorandum from the general manager of KNOW radio station. "Several factors indicate that radio station KNOW should shift its programming from rock-and-roll music to a continuous news format. Consider, for example, the number of older people in our listening area has increased dramatically, while the total number of our listeners has recently declined. Also, music stores in our area report decreased sales of recorded music. Finally, continuous news stations in neighboring cities have been very successful, and a survey taken just before the recent election shows that local citizens are interested in becoming better informed about politics."
