Challenge of the Yukon began on Detroit's radio station on WXYZ in 1938. (WXYZ was also the station that launched The Lone Ranger and The Green Hornet.) In 1947 Quaker Oats became the sponsor and the show moved to ABC, expanding the program from 15 minutes to 30 minutes. In 1950, Challenge of the Yukon was retitled to the now more familiar Sergeant Preston of the Yukon, airing now three times a week. It aired on the Mutual Broadcasting System from 1950 to its end in 1955.
This episode, "Man in Hiding," aired on October 9, 1951. Paul Sutton played Sergeant Preston and the part of Yukon King was played a sound effects man, either Dewey Cole of Ted Johnson.
Now, "On, King! On, you huskies!"
'Well, King this case is closed.'
