 One of the first two color television series on network television,  it was televised live at 4:30 p.m. Monday through Friday, using the  CBS field sequential color system, to a small network of CBS  affiliates on the East Coast. However, as the CBS field sequential  color television system was not visible on standard black and white  sets, it had a very limited audience of viewers watching on  prototype color models. The last show was on 14 September 1951.
