Ghostwriter is a television series co-produced by the Children's Television Workshop (now known as Sesame Workshop) and the BBC, originally aired on PBS in the United States from October 1992 to February 1995. The series features a group of New York City teenagers who solve mysteries with the help of an invisible ghost, who can communicate with the kids only by manipulating whatever text and letters he can find and using them to form words and sentences.
The series was designed to teach reading and writing skills to elementary and middle school children. Each mystery was presented as a story arc, covering four or five thirty-minute episodes; children were encouraged to follow each mystery, and use the reading and writing clues given to attempt to solve them just as the Ghostwriter team does in the show. Ghostwriter was critically acclaimed and honored for presenting a realistic, racially diverse world in its two-hour mystery stories. By the end of its third season, Ghostwriter ranked in the top five of all children's shows on American television. The program was cancelled after the third season, not because of a lack of popularity, but because of a lack of funding.
