"La cuarta parte" was started as a section of La bola de cristal (1984) on February 23, 1985. At the beginning of season 2 of "La bola de cristal", it was decided to split "La cuarta parte" from the rest of the show as its own program, because there were some concerns that some of its contents could be deemed a little inappropriate for the younger audiences that watched the earlier sections of "La bola de cristal".
After the third section of "La bola de cristal", the show ended, its credits were rolled, and then "La cuarta parte" began. It is sometimes considered as part of "La bola de cristal", as it was done by the same team, sharing some of the actors, and was always broadcast after it, but this is only true in season one of "La bola...", they were officially different shows from October 1985.
