Just noticed its the 20th anniversary of The Simpsons this year.
Season 21 starts September 27.
QuoteThe Simpsons' twenty-first season will air on Fox starting on September 27, 2009. The season will establish The Simpsons as the longest running American primetime television series, replacing Gunsmoke for that distinction.QuoteIn 2009, to celebrate the 20th anniversary of the premiere of The Simpsons, Fox announced earlier in the year that a year-long celebration of the show titled "Best. 20 Years. Ever." would run from January 14, 2009 to January 14, 2010. As part of the celebration, documentary filmmaker Morgan Spurlock will direct and produce The Simpsons 20th Anniversary Special in 3-D on Ice, a documentary special that will examine the "cultural phenomenon of The Simpsons". It will air on January 14, 2010 on Fox. In February 2009, Spurlock was asked to direct the special. The producers spent several months deciding on the content and format of the film, and production is set to begin at Comic-con 2009. It will include interviews with the cast and fans of the show. Despite the title, Spurlock says the special "most likely will not be in 3-D nor on ice."
