Elmo is currently one of the main characters on "Sesame Street". He was just a background monster when he first appeared in the late 1970s However, when Richard Hunt decided to not perform Elmo, he gave the character to Kevin Clash, and asked him to create a voice. Thus, Elmo was revamped.
Now, he has become a major character, getting most of the episode plots and merchandise credits. In 1998, he received his own 15-minute segment, Elmo's World. Elmo first appeared as Baby Monster, and he was performed by Jerry Nelson. He also has a girlfriend named Zoe, though on the show they appear to be just friends.
