Bonanza as "Bonanza". In the fall of 1972, off-network episodes were released in broadcast syndication to local stations by NBC under the "Ponderosa" name. After the series was canceled, the syndicated reruns reverted to the "Bonanza" name. From the fourth season on, the Cartwrights and nearly every other recurring character on the show wore the same clothing in almost every episode. The reason for this is twofold: it made duplication of wardrobe easier for stunt doubles (Hal Burton, Bob Miles, Bill Clark, Lyle Heisler, Ray Mazy) and it cut the cost of refilming action shots (such as riding clips in-between scenes),
Bonanza 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
