Dr. I.Q. was a radio and television quiz program that featured a simple yet appealing format that captivated audiences from 1939 to 1959. The show's premise involved selecting audience members as contestants and asking them various questions. Host Lew Valentine, alongside his microphone-wielding assistants, engaged contestants and awarded cash prizes in the form of silver dollars and Mars Candy's Snickers bars. The show included features like the "Biographical Sketch," where contestants were given clues to identify a person, and the "Lady in the Balcony" quiz, which featured consecutive weekly appearances for a female contestant aiming to win a jackpot prize.

The radio version of Dr. I.Q. was broadcast from various concert halls and theaters in different cities, without a set studio, and aired on NBC and ABC networks from April 10, 1939, until November 29, 1950. Hosts during the radio show's run included Lew Valentine, Jimmy McClain, and Stanley Vainrib. Dr. I.Q. Jr., a juvenile version of the show, aired on NBC from 1941 to 1949, with Valentine and McClain as hosts. The television incarnation of Dr. I.Q. aired on ABC from November 4, 1953, to October 17, 1954, and again from December 15, 1958, to March 23, 1959. Jay Owen, James McClain, and Tom Kennedy all served as hosts during the TV show's run, and Hazel Bishop cosmetics was a sponsor of the program in 1954. Only one episode from the 1953-54 version and four episodes from the 1958-59 version, along with a pilot for Dr. I.Q. Jr., are known to still exist today.
