Chandu appeared during two different radio listening eras, with various sponsors, the first from 1932-36 and the second from 1948-50. The show listed below was sponsored by White King Soap Flakes.
This program was on the air at various times between the years 1935 and 1948 with different sponsors. The following shows offering premiums were sponsored by Quaker Puffed Wheat and Rice cereals. All concerned Dick Tracy's adventure with the Black Pearl of Osiris.
While not covered in this broadcast, we can see what was necessary to achieve these high honors by looking through the 1938 edition of the code book. Additional ranks included Sergeant, Lieutenant, Captain and Inspector-General, and each level sported a fancier and gaudier badge to note the new office. To progress, members needed to write Dick and tell him of any good deeds since their last promotion and, by the way, include additional box tops for each level. Sergeant required 5 box tops, Lieutenant 7, Captain 10 and Inspector-General a whopping 15 box tops. If a member decided to form his own patrol and apply for the Patrol Leader badge, he needed to recruit 5 new members, at 2 box tops each, plus another 2 for himself, for a total of 12 box tops in all. That's a total of 41 box tops to achieve all the ranks and honors, not counting the 10 additional box tops friends should have contributed to join the local patrol. When the announcer said Dick wanted members tell him the stuff they were made of, the answer should have been obvious.
