Commonly the effect of animation is achieved by a rapid succession of sequential images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon and beta movement, but the exact causes are still uncertain.
Analog mechanical animation media that rely on the rapid display of sequential images include the phénakisticope, zoetrope, flip book, praxinoscope and film. Television and video are popular electronic animation media that originally were analog and now operate digitally. For display on the computer, techniques like animated GIF and Flash animation were developed.
Eric Cartman is a fictional character on the Americananimatedtelevision seriesSouth Park. One of four main characters, along with Stan Marsh, Kyle Broflovski, and Kenny McCormick, he is often portrayed as the series' main anti-hero and in opposition to his friends, who commonly refer to him by his last name. He debuted on television when South Park first aired on August 13, 1997; he had earlier appeared in The Spirit of Christmas shorts created by Trey Parker and Matt Stone in 1992 (Jesus vs. Frosty) and 1995 (Jesus vs. Santa). Voiced by Trey Parker, Cartman is an overweight, immature, spoiled, lazy, foul-mouthed, mean-spirited, racist, sexist, anti-semitic, sociopathic, narcissistic, and ill-tempered third- then fourth-grader living with his mother in the fictional town of South Park, Colorado, where he routinely has extraordinary experiences not typical of conventional small-town life. Cartman is one of the most popular characters on the show, and has remained one of the most recognizable television characters ever since South Park became a hit during its first season. Parker and Stone describe the character as "a little Archie Bunker", and state that he is their favorite character, and the one with whom they most identify. During its fifteen seasons, South Park has received both praise and criticism for Cartman's tendency to be politically incorrect and shockingly profane. Prominent publications and television channels have included Cartman on their lists of the most iconic television and cartoon characters of all time.

He was born and raised in Detroit, Michigan and graduated from Harvard University in 1981. Jean began his writing career in the 1980s with fellow Harvard alum Mike Reiss. It was first broadcast on ABC in January 1994 and was well-received by critics, but did not catch on with viewers and only lasted for two seasons. In 1994, Jean and Reiss signed a three-year deal with The Walt Disney Company to produce other television shows for ABC and the duo created and executive produced Teen Angel, which was canceled in its first season. Jean returned full-time to The Simpsons during the tenth season (1998).

Jean was also one of the writers and producers that worked on The Simpsons Movie, a feature-length film based on the series that was released in 2007.
