The CW’s The Vampire Diaries/The Originals spinoff Legacies would love to have Fam’s viewers and ratings; the March 7 episode of Legacies — which competes with Fam in its second half — earned 0.85 million viewers and a 0.2 rating.
The Vampire Diaries ended its 2009-2017 run with a March 2017 Season 8 finale that had 1.15 million viewers and a 0.5 rating.
As one of the major networks, CBS has different standards than The CW.
But Legacies has already been renewed for Season 2.
