Shaw attended the University of Oklahoma, where she earned a degree in journalism while participating in the university's radio station, and began working at WKY Radio in 1976. There, she was a news presenter until being laid off when the station switched to FM format; however, at that time, the WKY-TV station was located in the same building, and she began working there instead.
After seven years at WKY-TV, during which she was only given shifts on weekends, Shaw concluded that WKY offered her no chance for career advancement, and applied to the then-nascent Cable News Network, on the grounds that "Ted Turner was hiring a lot of people from Oklahoma". Shaw's first day at CNN was July 12, 1984; although she had not been scheduled to appear on-camera that day, the regular news presenter was temporarily unavailable, and Shaw was chosen to report the news that Walter Mondale had selected Geraldine Ferraro as his running mate for the 1984 presidential election.
In 1989, she became the co-host of CNN's Showbiz Today, replacing Bill Tush; however, in 1993, CNN chose not to renew her contract, replacing her on Showbiz Today with Jim Moret, which Variety attributed to Moret being perceived as "more serious" than Shaw.
