A Charlie Brown Christmas uses a cast of amateur child voice actors, deals with the theme of seasonal depression, and culminates in the recitation of a Bible verse, all to a jazz score. It was not, safe to say, the special that CBS had expected, to say nothing of its sponsor, the Coca-Cola Company. In all likelihood, it would have been canceled, but seeing as it had already been announced and promoted (and in any case, was completed only a few days before it was scheduled to air), the show went on.
