Jack FM is a radio network brand, licensed by Sparknet Communications, with the exception of the European Union where it is licensed by Oxis Media. It plays an adult hits format, in most cases not using DJs. Format characteristics Stations using the "Jack" name are strictly licensed by SparkNet Communications. There are several terms that each station must agree to, including the use of no disc jockeys for at least the first few months of the format. SparkNet has been protective of its format, unsuccessfully filing trademark infringement suits against Bonneville International for its use of the Jack FM trademarked slogan "Playing What We Want" and other similar phrases. For this reason, many stations airing a Jack-like format use slightly different slogans to avoid infringing on SparkNet's service marks: WBEN-FM in Philadelphia uses the tagline "Playing anything we feel like." On WLKO "102.9 The Lake" in Charlotte, North Carolina, the tagline is "We Play Anything". During its run as "Doug FM", WDRQ in Detroit used the line "93.1 DOUG FM - We Play...EVERYTHING!" As the voice of "Jack," most stations in the United States use Howard Cogan and Andrew Anthony (best known as the voice of EA Sports and GEICO), while stations in Canada use Greg Beharrell. Meanwhile all Jack FM stations in the United Kingdom used former Blake's 7 actor Paul Darrow as the voice of Jack. In place of DJs, the Jack character makes sarcastic or ironic remarks and quips, often using self-deprecating humor. Each September of every year, all Jack FM stations ask their listeners to visit a certain link to evaluate which songs should be played on the radio and which ones should be swapped. Changes take effect usually a few weeks to two months after the results are finalized. History 2000–2003: Origins One of the early originators of the Jack FM format was radio programmer Bob Perry, on a United States-based Internet radio stream in 2000. Perry named the station after a fictitious persona, "Cadillac Jack" Garrett, "a hard-living radio cowboy". The back story created by Perry for the original webstream was that Garrett, a disc jockey who had worked many "big sticks", finally got his own radio station and after years of being told what he was to play on-air was creating a station where the motto was "playing what we want".
