In this 1994 letter to Reader's Digest, Peggy Carter of R.J. Reynolds' Media Relations Department tried to argue that RJR sponsored the early 1960s cartoon show "The Flintstones" to appeal to an adult audience. Carter explains that show show contained "adult themes":
"...the show was molded after Jackie Gleason's popular sitcom, The Honeymooners. Besides being billed as the first adult cartoon show, The Flintstones featured adult themes, including marital squabbles, family rivalry and job difficulties. The show aired dcuring prime time at 8:30 p.m., not among youth programming."
