The Western film genre declined in the late 1940s, and Hayes made his last film appearance in The Cariboo Trail (1950). He moved to television and hosted The Gabby Hayes Show, a Western series, from 1950 to 1954 on NBC and, in a new version in 1956, on ABC. The show was sponsored by Quaker Oats, whose products were prominently advertised during the show. Gabby would promote the puffed wheat product by saying to stand back from the screen and firing a cannon loaded with cereal at the screen as a tie in to their ad slogan ‘shot from a guns’. He introduced the show, often while whittling on a piece of wood, and would sometimes throw in a tall tale. Halfway through the show, he would say something else, and at the end of the show, also, but he did not appear as an active character in the stories. When the series ended, Hayes retired from show business. He lent his name to a comic book series, "Gabby Hayes Western" comics, published by Fawcett Publications from November 1948 until January 1957, and to a children's summer camp in New York.
