The program spawned the Davy Crockett craze of 1955 with the airing of a three-episode series (not shown over the course of consecutive weeks) about the historical American frontiersman, starring Fess Parker in the title role. Millions of dollars of merchandise relating to the title character were sold, and the theme song, "The Ballad of Davy Crockett", became a hit record that year. Three historically based hour-long programs aired during late 1954/early 1955, and were followed up by two dramatized installments the following year. The TV episodes were later edited into two theatrical films.
