Bonanza
The family lived on a thousand square-mile (2,600 km) ranch called the Ponderosa on the eastern shore of Lake Tahoe in Nevada opposite California on the edge of the Sierra Nevada range]. The vast size of the Cartwrights' land was quietly revised to "half a million acres" (2,000 km) on Lorne Greene's 1964 song, "Saga of the Ponderosa." The ranch name refers to the Ponderosa Pine, common in the West. The nearest town to the Ponderosa was Virginia City, where the Cartwrights would go to converse with Sheriff Roy Coffee (played by veteran actor Ray Teal), or his deputy Clem Foster (Bing Russell).
1970s in television
With the rise in socially responsible programming, the television western, a very popular genre in the 1960s, slowly died out. The first casualties were "The High Chaparral" and "The Virginian", both NBC staples, in the spring of 1971. "Bonanza" suffered a blow when actor Dan Blocker died during surgery in 1972, and the show quietly ended its run the next year. CBS's "Gunsmoke" outlasted them all, and finally ended its run with a star-studded series finale in 1975. "Bonanza" actor Michael Landon helped popularize a television adaptation of the popular children's book series "Little House on the Prairie". Debuting in 1974, the series ran for eight years. "Little House"'s competitor family drama was CBS's "The Waltons", which revolved around family unity but during a different time and place — Virginia during the Great Depression.
