On December 24, 1925, seventeen local businesses backing The Voice of St. Louis, Inc., launched their new radio station KMOX. Broadcast pioneer William Paley owned the station by 1932 and later nicknamed it "the jewel in the CBS crown."
Young guitarist Les Paul worked at KMOX using the name "Rhubarb Red." Dr. Tom Dooley reported for KMOX from the jungles of Southeast Asia. The first CBS station to air editorials and endorse candidates, KMOX added in 1960 its "At Your Service" show, a forebear of talk radio.
KMOX introduced Bob Costas, Jack Buck, Harry Caray, Joe Buck, Joe Garagiola, Dan Dierdorf, Dan Kelly, Skip Casey and countless others in St. Louis and beyond on its 50,000 "red hot" watts.
