Myron Cope (January 23, 1929 – February 27, 2008) was an American sports journalist, radio personality, and sportscaster. He is best known for being “the voice of the Pittsburgh Steelers”.
Cope was a color commentator for the Steelers’ radio broadcasts for 35 years. He was known for his distinctive, higher-pitched nasally voice with an identifiable Pittsburgh accent, idiosyncratic speech pattern, and a level of excitement rarely exhibited in the broadcast booth. Cope’s most notable catch phrase was “yoi”. He helped popularize the Terrible Towel, a rally towel associated with the Steelers. In 1996, Cope gave the rights to the towel to Allegheny Valley School, which has received more than $6 million in proceeds from towel sales.
Cope was the first football announcer inducted into the National Radio Hall of Fame. Cope’s autobiography, Double Yoi!, was published in 2002.
