Why was Nat king col es musical variety show cancelled in 1958?

Nat King Cole's musical variety show was canceled in 1958 primarily due to declining ratings and challenges in attracting a wider audience. Despite being popular with some viewers, the show struggled with the changing television landscape and competition from other programs. Additionally, the show faced racial prejudices, as Cole, an African American artist, encountered difficulties in appealing to a predominantly white audience in the segregated America of that era.
