The first serial considered to be a "soap opera" was Painted Dreams, which debuted October 20, 1930 on Chicago's WGN. Early radio series such as Painted Dreams were broadcast in weekday daytime slots, usually five days a week, when most listeners would be housewives; thus the shows were aimed at and consumed by a predominantly female audience. The first national radio soap opera was Clara, Lu and Em, which aired on the NBC Blue Network at 10:30 pm on Tuesday, January 27, 1931.
