CBS Radio revived "Yours Truly, Johnny Dollar" in October 1955 with a new leading man, a new director, and a new format. The program changed from a 30-minute, one-episode-per-week program to a 15-minute, five-nights-a-week serial (Monday through Friday, 8–8:15 pm EST) produced and directed by radio veteran Jack Johnstone. The new Johnny Dollar was Bob Bailey, who had just come off another network detective series, "Let George Do It". With a new lead and 75 minutes of air time each week, it became possible to develop each storyline with more detail and with more characters. Almost all of the Johnny Dollar serials were presented by CBS Radio on a sustaining basis (unsponsored, with no commercials); only two of the 55 serials take time out for a sponsor's message.
