Memorialized along with fellow contemporary WGN children's series The Ray Rayner Show and Garfield Goose & Friends in the 2005 two hour TV special Bozo, Gar, and Ray: WGN TV Classics, which looks at the history and impact of all three series (though primarily Bozo), along with numerous surviving clips and bloopers from the three series. This is aired twice a year annually during the holiday season. WGN has since aired a complete Bob Bell-era episode of Bozo's Circus and a 1960s compilation special, both found within the station's archives.
Like Romper Room, Bozo's Circus/The Bozo Show is a franchised show, meaning individual stations could do their own version of the show, but Chicago's was by far the longest running and best recognized, especially by the 1980s when WGN was carried as a superstation by cable providers across the country.

- Christmas Episode: They did a Christmas episode during Christmas of each year and ran some Christmas cartoons (such as Hardrock, Coco, and Joe: The Three Little Dwarfs, Suzy Snowflake, and the UPA version of Frosty the Snowman).
- Christmas Special: The 2005 retrospective special Bozo, Gar, and Ray: WGN TV Classics features the three aforementioned Christmas cartoons in their entirety, plus a clip of Ray Rayner singing "White Christmas". While the special as a whole isn't otherwise seasonal in tone, WGN only airs it on Thanksgiving afternoon and just before Christmas each year, ensuring that it remains a special to watch at the holidays with your family, and this angle is promoted in commercials for the yearly airings.
