The character was created by Alan W. Livingston, and portrayed by Pinto Colvig for a children's storytelling record album and illustrated read-along book set in 1946.
In 1948, Capitol and Livingston began setting up royalty arrangements with manufacturers and television stations for use of the Bozo character.
Harmon renamed the character "Bozo, The World's Most Famous Clown" and modified the voice and costume, also changing the laugh to a distinctively hoarse, slightly deranged chuckle.
He then worked with a wig stylist to get the wing-tipped bright orange style and look of the hair that had previously appeared in Capitol's Bozo comic books.
Bozo's headpiece was made from yak hair, which was adhered to a canvas base with a starched burlap interior foundation.
[6] The show's distribution network included New York City, Los Angeles, Washington, D.C., and Boston at one point, though most television stations still preferred to continue producing their own versions.
The most popular local version was Bob Bell and WGN-TV Chicago's Bozo's Circus, which went national via cable and satellite in 1978.
The WGN version successfully survived competition from syndicated and network children's programs until 1994, when WGN management decided to exit the weekday children's television business and buried The Bozo Show in an early Sunday timeslot as The Bozo Super Sunday Show.
In 2001, station management controversially ended production, citing increased competition from newer children's cable channels.

[25] Four months later, WGN-TV paid tribute to Sandburg and the rest of the original cast with a two-hour special titled "Bozo's Circus: The 1960s."
Brazil's Bozo shows ended in 1991, following the death of Décio Roberto, the last actor to portray the clown in that country.
Brazil's Bozo won five Troféu Imprensa, a Brazilian award given to personalities and productions in the media (in 1984, 1985, 1986, 1987 and 1989), as well as three Gold Albums.

After that, José Manuel Vargas Martínez, under sponsorship by Antonio Espino (famous comedy actor of the late 1940s and 1950s, known by his nickname, Clavillazo), portrayed the character.
In Mexico, television star, comedian and political commentator Víctor Trujillo created the character "Brozo, El Payaso Tenebroso" (Brozo, the Creepy Clown) in 1988 as a parody of Bozo for a TV Azteca program with Ausencio Cruz called La Caravana (The Caravan).
He pleased the audience with double-entendres and adult humor, telling sarcastic and sometimes obscene versions of classic children's tales.
Immediately following Willard Scott's three-year-run as WRC-TV Washington, D.C.'s Bozo, the show's sponsors, McDonald's drive-in restaurant franchisees John Gibson and Oscar Goldstein (Gee Gee Distributing Corporation), hired Scott to portray "Ronald McDonald, the Hamburger-Happy Clown" for their local commercials on the character's first three television "spots".
In the mid-1960s, Andy Amyx, performing as Bozo on Jacksonville, Florida, television station WFGA, was hired to do local appearances of Ronald McDonald periodically.
WGN's Bozo show is recognized as the most popular and successful locally produced children's program in the history of television, boasting a 10-year-wait for studio audience reservations and over 40 years in production.)
