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 "Sti skia tou hrimatos" ("Money Shadows"), which ran from 1990 to 1991. September 1991 saw the debut of "Lampsi" ("the Shining"), from creator Nicos Foskolos. The series would become Greece's longest-running soap opera. After the success of "Lampsi" came the short lived "To galazio diamandi" ("Blue Diamond") and "Simphonia siopis" ("Omertà"). "Lampsi" was canceled in June 2005 due to declining ratings. It was replaced by "Erotas" ("Love"), a soap that ran from 2005 to 2008. After that series ended, ANT1 abandoned the soap opera genre and focused on comedy series and weekly dramas. Greece's second longest-running soap is "Kalimera Zoi"
