The shows were not entirely live, however. With the exception of "All in the Family", sweetening was still a necessity during post-production in order to bridge any gaps in audience reactions. Television/laugh track historian Ben Glenn II observed a taping of the sitcom "Alice" (CBS, 1976–85) and noted the need for sweetening: "The actors kept blowing their lines. Of course, by the third or fourth take, the joke was no longer funny. A Douglass laugh was inserted into the final broadcast version to compensate."
