Succession is an American comedy-drama series about the Roy family, who are fighting for control of the family business amid uncertainty about the health of the family's patriarch, Logan Roy.
In "Must Love Dogs", Chris tells Stewie that he's not the one who stole his Halloween candy and that it was Peter, noting that they have to look out for each other, like the people on Succession.
When Lois orders Peter not to order pizza in "The Lois Quagmire", he retaliates by tweeting mean things to celebrities that look like her, including Sarah Snook, who uses the opportunity to pitch Succession. Peter points out that her father is stringing her along and she'll never get control of the company, which gets a like from Kendall Roy.
Family Guy performs an extended parody of Succession in "HBO-No".
