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).
Temperatures Rising
ABC placed "Temperatures Rising" in its 8:00 PM Tuesday night time-slot, where it debuted on September 12, 1972. Because one of the stars was black, some of ABC's affiliated stations in the southern and midwestern parts of the United States refused to air the series or broadcast it in a different time slot. Airing opposite it were "Bonanza" on NBC, and the new sitcom "Maude" on CBS. "Bonanza" was entering its fourteenth year and offered up an ambitious two-hour season premiere dealing with the marriage of Little Joe Cartwright (Michael Landon). "Maude", starring Beatrice Arthur in the title role, was a spin-off of "All in the Family". Both shows presented "Temperatures Rising" with stiff opposition in the "ratings game". The two-hour season premiere of "Bonanza" performed exceptionally well in the ratings. "Maude" did much better than "Temperatures Rising" in the New York City area, while "Temperatures Rising" fared better than "Maude" in the Los Angeles area. In subsequent weeks, "Bonanza"'s ratings dropped sharply and NBC cancelled the series in November 1972. According to Asher: ""Temperatures Rising" put "Bonanza" out of business and was beating "Maude" in the Los Angeles area until mid-season, when NBC switched to some heavy movies which hurt us". Despite this the series finished its first year with a consistent 29 share of the ratings at a time when a 30 share was enough to assure renewal for another season. ABC, however, wanted to improve the ratings and decided to make significant changes to "Temperatures Rising" for its second season.
