Yellowstone spinoff 1923 was created due to a misunderstanding from Paramount executives. The success of the original series led to multiple spinoffs, including 1883 and 1923. However, confusion arose when the limited series 1883 was renewed for a second season, leading to the creation of 1923. Despite the upcoming end of the original Yellowstone series, the franchise is expected to continue with the success of the spinoffs. The popularity of 1923 proves that the Yellowstone brand can thrive without the main series.
