During his years as the Speedway's announcer, Carnegie witnessed and reported many changes, including the introduction of new technology and real-time, electronic updates of race events that eventually decreased the fans' reliance on Carnegie's announcements. He was also on hand to witness many Speedway firsts including the debut in 1977 of Janet Guthrie, the first woman driver at the Indianapolis 500-mile race, and the introduction of NASCAR events at the Speedway with the debut of the Brickyard 400 in 1994, among others. The last time race fans heard Carnegie say "It's a new track record!" during qualifications was for driver Arie Luyendyk in May 1996. Carnegie retired from his work at the Speedway in 2006.
