John Clinton Formby, known as Clint Formby (December 22, 1923 – July 31, 2010), was a veteran radio broadcaster called the "Old Philosopher" based in the small city of Hereford, Texas, the seat of Deaf Smith County in the Texas Panhandle. His daily broadcast ran continuously on his KPAN AM & FM country-music station since October 10, 1955. Eventually reduced to five minutes in length, Formby's commentary was the oldest continuously-running broadcast by a single host in radio history.
