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. For all but the first three years of the show, it was hosted by Betty Lou Varnum, a pioneer in central-Iowa broadcasting.
Betty Lou Varnum, who is best known for The Magic Window, but was versatile enough to host such other shows as a teen dance party, election coverage, and a call in 'issues' show, hosted the show, along with a cast of puppets such as Gregory Lion, Dusty the Unicorn, and Catrina Crocodile. The heart of the show was Betty Lou teaching kids a new craft each episode. The puppets would help out by opening the curtain to the screen on which various featurettes were shown. These included episodes from Tales of the Riverbank, Felix the Cat, and a series called "Let's Be Friends" which introduced viewers to a child from another city or country, sharing their culture and lifestyle.
