The phenomenon where a sitcom character is erased from the show's history is named after whom?

• Chuck Cunningham:Fans of the show "Happy Days" might remember Charles Cunningham from the first season of the show. "Chuck" was the older brother of Richie and Joanie Cunningham and appeared in eleven episodes during the first season. However, by the time season two debuted, Chuck was nowhere to be found and never mentioned again. Chuck's disappearance without explanation gave rise to the term the "Chuck Cunningham Syndrome". The term is used to describe a character that simply disappears from a television show to the point where later episodes are scripted as if the character never existed at all.
