It is one of the longest-running scripted television programs in the world, airing nearly every weekday since November 8, 1965. A co-production of Corday Productions and Sony Pictures Television, the series was created by husband-and-wife team Ted Corday and Betty Corday. During Days of Our Livesearly years, Irna Phillips (creator of former NBC stablemate Another World as well as its former CBS rivals, As the World Turns and Guiding Light) served as a story editor for the program and many of the show's earliest storylines were written by William J. Bell, who would depart the series in 1975 to focus full-time on The Young and the Restless, which he created for CBS in 1973. Following the 2007 cancellation of Passions, Days of Our Lives remains the only soap opera airing on NBC.
