news staff broke the story about chemical contamination in the underground aquifers of southern Tucson, news items that prompted a major political controversy and subsequent cleanup. It also won investigative awards for breaking and following up on the story of a factory that painted glow-in-the-dark watch dials and instrument panels using tritium, a radioactive isotope that was found in school lunches prepared in a commissary across the street. Throughout the entire period from the 1970s until the Arizona Diamondbacks came into existence, KTUC was the Tucson affiliate of the Los Angeles Dodgers radio network syndicated from KABC radio in Los Angeles. The station also carried California Angels broadcasts picked up from KMPC in Los Angeles, and would tape delay the Angels games, or air them on sister station KFMM, when the Dodgers were on the air. In the days before cable television, when baseball games could be only be seen once a week on Major League Baseball on NBC, the Dodgers and Angels radio broadcasts developed a popular following in Tucson. 1970s sports director Rory Markas went to the 2002 World Series to cover the Angels for KTUC. General manager Tom Maples vowed he could sell ads for a play-by-play of two kids playing basketball with peach basket hoops. KTUC, while under Maples's leadership, aired live play-by-play of high school football and basketball games for many years sponsored by the KTUC Sports Boosters, mostly made up of small businesses throughout Tucson. In the late 1980s, the station was the Tucson affiliate of the Arizona State University Sun Devils radio network. In the 1990s, the station reversed affiliations and became the flagship of the Arizona Wildcats. KTUC also was the Tucson affiliate of the Phoenix Suns radio network. Switch from Talk to Standards On January 21, 1998, Sloane Broadcasting bought KTUC and its FM sister station 97.5 KOAZ (now KSZR) for $6.5 million. Sloane switched KTUC's format from talk to adult standards. In 2001, KTUC was acquired by Citadel Broadcasting, a forerunner to today's Cumulus Media. Citadel and Cumulus continued the adult standards format, aimed at older listeners and retirees who have settled in the Tucson metropolitan area.
