The episodes run a half-hour, including commercials. During PBS airings, these are replaced by segments that include "The Liberty News Network" or LNN (a newscast delivered by Cronkite summarizing the events of the episode, with each including his trademark sign-off "that's the way it is"), "Mystery Guest" (a guessing game where the kids guess a historical figure, who often is a character in the episode), "Now and Then" (a segment comparing life in the Revolutionary Era and today), and "Continental Cartoons" (a rebus word guessing game). The LNN segments were produced and art directed by designer Mike Bundlie.
