is known to differ from the CBS Television Quiz in its use of lockout buzzers, which had not yet been invented in 1941 (the first game show to use them was 1946's Winner Take All).
[4][5] Televised game shows prior to the debut of CBS Television Quiz were "test episodes" for experimental purposes; one of these was Truth or Consequences (NBC Radio, July 1, 1941), while a show called Spelling Bee was broadcast (BBC, 1938).
On October 2, the series moved to Thursdays, and on January 8 the show was reduced to 55 minutes for the network to present a five-minute news summary at 9:25 PM.
After WCBW scaled back their programing at the end of May 1942 following a mandate several weeks earlier by the War Production Board to cease building television stations, Quiz moved to Thursdays and Fridays and was again reduced to 50 minutes.
The series ended on January 7, 1943, the day before WCBW temporarily shut down its studios and reverted to broadcasting only filmed material on an irregular basis until May 1944.
