The daytime serial "Another World" (1964) was conceived as a spinoff of this show. It was submitted to CBS, which decided not to air the new program. After "Another World" was picked up by NBC, CBS refused to allow any major characters from this show to appear on the new one. However, one minor character, Mitchell Dru (Geoffrey Lumb), who had also appeared on the CBS soap opera "The Brighter Day" (1954), did appear on 'Another World".
Since the cancellation of "Another World" (1964) in 1999, several characters from that show (Jake, Cass, Vicky, Donna and Marley) have made appearances on this one.
One of the first two half-hour soap operas in television. (The other being "The Edge of Night" (1956), which premiered the same day.)
The first CBS soap opera to expand to one hour (1 December 1975) and the third soap opera to expand to one hour in television history. The first was "Another World" (1964) and the second was "Days of Our Lives" (1965).
Regular color broadcasts began on 20 March 1967.
The episode of 22 November 1963 was broken into by CBS to announce the assassination of President John F. Kennedy. The actors, however, continued performing (as it was done live until 1975), and a complete, uninterrupted copy of this episode still survives.
