Bonanza was aired from 1959 until 1973 with a grand total of 14 seasons containing 431 episodes altogether. This famous TV show was the second longest-running Western on TV, right after the famous show Gunsmoke.
It's time for some Bonanza trivia! The show is mainly about the "Cartwright" family and their weekly shenanigans at their ranch near Lake Tahoe, Nevada. It stars "Ben Cartwright," who has been widowed three times, and his three sons, "Adam," "Hoss," and "Little Joe," along with a supporting cast of a few other characters.
