query: When did the radio station WEEI first air?
passage: WEEI (AM)
WEEI traces its roots to its original owner, Edison Electric Illuminating Company of Boston (hence the call letters). Edison placed the station on the air September 29, 1924.[1][3] The station broadcast on various frequencies over the next several years, settling on 590kHz in 1927.[1] In 1926, WEEI became a charter member of the NBC Red Network[1] and remained an NBC Red affiliate until 1936, when the station was leased by CBS and became an affiliate of that network.[4] CBS bought WEEI outright from Boston Edison on August 31, 1942.[5] An FM sister station, WEEI-FM (103.3 FM, now WODS), went on the air in 1948.[6] Until 1960, WEEI, through CBS Radio, was the last Boston radio station to devote a large amount of its program schedule to "traditional" network radio programming of daytime soap operas, comedy shows, variety shows, and similar fare.
passage: WSOO
Broadcasting since June 25, 1940, WSOO is the first radio station to broadcast in the Sault Ste. Marie, Michigan radio market, and was only preceded in the region by the now-closed Sault Ste. Marie, Ontario AM station CFYN (formerly CJIC.) The station was launched and owned by the Hiawathaland Broadcasting Company, who later shifted the station to a middle of the road format in the late 1960s, prior to selling the station to Patterson Communications (later the Miami County Broadcasting Company) in 1971, as owned by Richard E. Hunt, who also owned WCBY AM & FM in Cheboygan and WPTW AM & FM in his hometown of Piqua, Ohio. WSOO was purchased by Fabiano-Strickler Communications in 1981, who shifted to its current adult contemporary/talk format in 1989. The station was ultimately purchased by current owners Sovereign Communications in 2003.
