Z Morning zoo is a format of morning radio show common to English-language radio broadcasting. The name is derived from the "wackiness and zaniness" of the activities, bits, and overall personality of the show and its hosts. The morning zoo concept and name is most often deployed on contemporary hit radio (CHR-Top 40) radio stations.
A morning zoo typically consists of two or more radio personalities, usually capable of spontaneous comic interaction as well as competent delivery of news and service elements. Most morning zoo programs involve scripted or live telephone calls, on-air games and regular contests.
