Bonanza
Following Canary's departure, Frizzell's character accompanied Jamie Hunter to the Ponderosa and became the Cartwright's foreman.Initially, "Bonanza" aired on Saturday evenings opposite "Dick Clark's Saturday Night Beech-Nut Show" and "John Gunther's High Road" on ABC, and "Perry Mason" on CBS. "Bonanza"s initial ratings were respectable, often coming in behind Mason but ahead of the ABC line-up. Ironically, executives considered canceling the show before its premiere because of its high cost. NBC kept it because "Bonanza" was one of the first series to be filmed and broadcast in color, including scenes of picturesque Lake Tahoe, Nevada, although most of the episodes were obviously filmed on soundstages until the seasons near the end of the series. NBC's corporate parent, Radio Corporation of America (RCA), used the show to spur sales of RCA-manufactured color television sets (RCA was also the primary sponsor of the series during its first two seasons).

In May 1972, Blocker died suddenly from a post-operative pulmonary embolism following surgery to remove his gall bladder. The producers felt nobody else could continue the role. It was the first time a TV show's producers chose to kill off a young major male character (though it was done twice previously with young female leads—in 1956 on "Make Room For Daddy", and again in 1963 with "The Real McCoys"). Not until the TV movie "" was it explained that Hoss had drowned attempting to save a woman's life.
