Soap operas originated in the 1920s United States as a genre primarily aimed at women broadcast on radio to advertise soap products. This targeting of women affected the scheduling and storylines, which focused on traditional female domestic roles and took place after mealtimes when women had free time. The continuous broadcast of soap operas over many years in the same time slots and on the same channels means they become deeply ingrained in culture. Viewers come to see the characters as real people and relate to or dislike the empathetic and often outrageous storylines that interweave between the large ensemble casts. Many viewers find catharsis and escapism by vicariously experiencing the dramatic problems of others through soap operas.
