Taylor Sheridan's most successful show so far is Yellowstone, but a new announcement about Tulsa King will break his four-year-long franchise trend. Yellowstone already has two spinoff shows - 1883 and 1923 - and there are more on the way. Some of the upcoming Yellowstone spinoffs include 6666, focusing on Jimmy's time in Texas, the Dutton Ranch spinoff focusing on Beth Dutton and Rip Wheeler, The Madison spinoff starring Michelle Pfeiffer, and Y: Marshals, focusing on Kayce Dutton. The Yellowstone franchise is frankly huge, and it's growing larger every day, even after the ending of the main Yellowstone series.
