Beginning with their very first broadcast public reaction to the Hoot Owls was instaneous and overwhelming. More than 90,000 membership applications were granted during the program's life. Members included jail inmates, presidents Harding and Coolidge, Admiral Byrd, the mayors of San Francisco and New York, prize fighters Gene Tunney, Gentleman Jim Corbett and Jack Dempsey, Babe Ruth, preacher Billy Sunday, showman Alexander Pantages and three Oregon governors. Many major entertainers, such as the Marx Brothers, were also Hoot Owls.
In Mexico City, a theatre would stop its movie when the program came on and play the Hoot Owls for the movie audience from an on-stage radio.
