  Knots Landing
  Prior to the premiere of Dallas, Jacobs originated the idea for a drama series about four married couples in different stages of marriage, inspired by Ingmar Bergman's Scenes from a Marriage. However, CBS wanted a "saga-like" show, resulting in Jacobs creating Dallas. When the series proved to be a hit, CBS reconsidered Jacobs's original idea, which evolved into Dallas spin-off series  Knots Landing, premiering in late 1979.
  Knots Landing followed the lives of Lucy's parents, Gary (Ted Shackelford) and Valene (Joan Van Ark), as they move to California to start a new life following the start of their second marriage in 1979. During the early seasons of Knots Landing, several Dallas actors (Larry Hagman, Patrick Duffy, Charlene Tilton, and Mary Crosby) made guest appearances in the new series, and Shackelford and Van Ark continued to make occasional appearances in Dallas. In addition to this, some storylines crossed over, such as the reading of Jock Ewing's will, with events having an impact on characters in both shows.
