Soap opera soap opera "Guiding Light" (originally titled "The Guiding Light" until 1975) started as a radio drama in January 1937 and subsequently transferred to television in June 1952. With the exception of several years in the late 1940s, during which creator Irna Phillips was involved in a dispute with Procter & Gamble, "Guiding Light" was heard or seen nearly every weekday from 1937 until 2009, making it the longest story ever told in a broadcast medium. Originally serials were broadcast as fifteen-minute installments each weekday in daytime slots. In 1956, "As the World Turns" and "The Edge of Night", both produced
Soap opera nights a week (on Monday through Fridays) in a manner similar to a daytime soap opera, instead of the once-a-week episode output common of other primetime soaps. The series, which was an adaptation of the Mexican telenovela "Alcanzar una estrella", suffered from low ratings (generally receiving less than one million viewers) and was later moved to sister cable channel TeenNick halfway through its run to burn off the remaining episodes. In 2015, Fox debuted "Empire", a primetime musical serial centering on the power struggle between family members within the titular recording company. Created by Lee Daniels and Danny Strong and
