Magicland was a television magic show for children that ran for 23 years on the Memphis, Tennessee, station WMC-TV. It holds the Guinness World Record for the longest continuously running television magic series in the world.
The show was created by presenter Dick Williams, who was recruited to WMC-TV in 1965 as a staff announcer and weatherman. Williams was a magician in his spare time and had started a magic show under the title Magicland for his previous station KGNC in Amarillo, Texas. Management at WMC-TV liked the sound of that show and persuaded Williams to create something similar for them. He agreed, but thought the series would only last for about a year. Instead it eventually ran for 23 years and nearly 1,200 episodes.
