Bozo the Clown
Bozo the Clown was another of the greatest clowns to ever appear on television. Although he may not be well-known to younger readers, Bozo was a common figure throughout the 1960s and 1970s. He had his own show in America called Bozo's Circus, which was followed by The Bozo Show, where he was portrayed by a number of actors. The success of Bozo the Clown led to the character being syndicated internationally, with Bozo appearing in places including Brazil, Mexico, Thailand, and Australia.
Bozo was dressed as a conventional clown, with white face paint, red hair that was curly, and a large red nose. Despite being adored by kids, he does have a scary appearance, so you can see why some kids might not have liked him. Given that the program ran for many years, his appeal to kids was apparent.
