also known as The House with the Magic Window) was an American children's television program broadcast on ABC affiliate WOI-TV in Ames, Iowa from 1951 to 1994. With a run of 43 years, it was the longest running children's television program in American history. (Bozo's Circus technically had a longer run; however, it was made in many different local markets by different producers.) Producer Dick Hartzell and WOI TV artist Joy (Ringham) Munn developed the show as an educational children's program, which featured handicraft activities, news items, and birthday recognition for the children viewing the show. Joy co-hosted the show with Craighton Knau for the first season (1951-1952), which was 30 minutes long and aired 3 times per week. During the second season, she became the sole host of the program. For that season the show was 15 minutes long and aired 5 days per week. Joy left the show in 1953. For all but the first three years of the show, it was hosted by Betty Lou Varnum, another pioneer in central-Iowa broadcasting.
