WFAA-TV began its rise to news dominance in Dallas–Fort Worth during the late 1960s and early 1970s under the leadership of news manager Travis Linn, who had previously served as news director for WFAA radio. Linn later became Dallas bureau chief for CBS News before becoming professor and dean of the journalism program at the University of Nevada–Reno. Under Linn, the station expanded its news programming to 4½ hours per day, including an unprecedented one-hour program at 10 p.m. each weeknight as well as a 15-minute newscast at midnight four nights a week; the station also launched "News 8 Etc.", a 90-minute morning news-talk show that replaced the children's program "Mr. Peppermint" in January 1970 and was originally hosted by Suzie Humphreys and Don Harris, who conducted the broadcast without the assistance of cue cards or a TelePrompTer; following anchor Gene Thomas' death when a jet-powered dragster he was riding in for a story being produced for the show crashed at speeds of at Dallas International Motor Speedway in October 1971, the program underwent several changes to its anchor team and was later retooled in May 1974 as "The AM Show" (later shortened to simply "AM"), before ending in January 1978.
