The Wallace and Ladmo Show, originally known as It's Wallace? and Wallace & Company, was a children's television show produced by and aired on KPHO-TV in Phoenix, Arizona, from January 24, 1955 to December 29, 1989. It’s widely said to have started on April 1, 1954, but Bill Thompson said he created the character of Wallace in 1954 and just said April 1 because it was funny.
