Named "Buzzco" after animation producer Buzz Potamkin, who founded the concern in 1982, the company was turned over to lead directors/designers Candy Kugel and Vincent Cafarelli and renamed Buzzco Associates in 1985. The studio, most of whose shorts are a collaboration between Kugel and Cafarelli, focuses on independent films and educational/industrial work, and also produced segments for CTW's Square One TV.
The studio renewed its Sesame Street association in 2005, with the short "I Eat the Colors of the Rainbow."
Buzzco's credits have also included countless commercials (some with famous characters like Betty Boop, Teenage Mutant Ninja Turtles, and Underdog), TV station IDs, and inserts, as well as traditional 2D animated effects for some live-action ads. The latter included a 1999 spot for the Magic Talking Kermit the Frog toy from Tyco, animating a fly for the Kermit toy to catch. 
The following shorts are all co-directed by Kugel and Cafarelli, generally with designs by Kugel.
