 With the rise of rock n' roll music, WKRP's "beautiful music" format became outdated and a sure money-loser, appealing only to senior citizens.In the pilot of "WKRP", the new program director, Andy Travis, convinces Mr. Carlson that switching the format to rock n' roll might make the station successful and profitable; Mr. Carlson, who wants desperately to prove to his mother that he can be a success, goes along with the change and even gets the nerve to defend Andy's changes to his mother.Only when Arthur shows that much backbone does his mother relent and keep to the format change.
