Yours Truly, Johnny Dollar was a radio drama about a freelance insurance investigator "with the action-packed expense account." The show aired on CBS Radio from February 11, 1949 to September 30, 1962. There were 811 episodes in the 12-year run, and over 720 still exist today. As originally conceived, Johnny Dollar was a smart, tough, wisecracking detective who tossed silver-dollar tips to waiters and bellhops. Dick Powell starred in the audition show, recorded in 1948, but withdrew from the role in favor of other projects. The role went instead to Charles Russell. With the first three actors to play Johnny Dollar -- radio actor Russell and movie tough-guy actors Edmond O'Brien and John Lund -- there was little to distinguish Johnny Dollar from other detective series at the time (Richard Diamond, Philip Marlowe and Sam Spade). While always a friend of the police, Johnny wasn't necessarily a stickler for the strictest interpretation of the law. He was willing to let some things slide to satisfy his own sense of justice, as long as the interests of his employer were protected. After a year-long break (August 1954 to August 1955), the show changed from a 30-minute, one-episode-per-week affair to a 15-minute, five-nights-a-week serial that introduced the most successful Johnny Dollar: Bob Bailey, who had just come off another network detective series, Let George Do It.
