Rick Dees Weekly Top 40
Rick Dees is a Los Angeles DJ who began his own weekly top 40 countdown in 1983. The "Weekly Top 40" is a mix of humor and chart information, and the show continues today. The show originally used the Cashbox charts, but switched to the Radio and Records Top 40/CHR chart. In 1994, ABC networks bought The Weekly Top 40 and decided to air that in the USA instead of American Top 40. At the beginning of 2000, Premiere Radio Networks became the owner of the show. Dees switched US syndicators in 2005.
Rick sometimes has specials instead of regular countdowns, e.g. a "Block Party All Request Special" or "The Hottest Hits of Summer Special". The show also has split into three versions, a Top 40 / Mainstream version, Top 40/Rhythmic version, and a Hot Adult Contemporary version. There is an official web site. In 2005, Dees began using his own chart not based on any magazine but based on affiliate airplay instead. Also, in 2005, the Hot AC version of the show expanded from a top 30 to a top 40. Rick has old editions of his countdown available each week on his app.
