The 1960s saw a return to "the more mundane sensibilities of comedy," due to viewers' wishes for television programming to be a "cultural antidepressant." Thus, fantasy- and rurally-oriented comedies gained popularity and dominated the Nielsen ratings. Like other comedies at the time, "Gomer Pyle" was a "deep escapist" show; it avoided political commentary and offered viewers a distraction from the social changes of the 1960s. Despite being a military-themed show and airing during the peak of the Vietnam War, the show never discussed the war. Instead, the show was founded on "Gomer's innocent simplicity Sergeant Carter's frustration and later concern for Gomer's well-being." This, compounded with the popularity of rural comedies in the 1960s, made the show popular. Frank Sutton, who played Carter, ascribed the show's popularity to its concentration on its two main characters, and the plots being built around their respective personalities. The program remained in the top 10 of the ratings throughout its run—in the top three for all but its third season when CBS moved it from Fridays to Wednesdays. Nabors quit because he desired to move to something else, 'reach for another rung on the ladder, either up or down'.
