Bonanza
Bonanza is an NBC television western series that ran from 1959 to 1973. Lasting 14 seasons and 431 episodes, "Bonanza" is NBC's longest-running western, and ranks overall as the second-longest-running western series on U.S. network television (behind CBS's "Gunsmoke"), and within the top 10 longest-running, live-action American series. The show continues to air in syndication. The show is set in the 1860s and it centers on the wealthy Cartwright family that live in the vicinity of Virginia City, Nevada, bordering Lake Tahoe. The series initially starred Lorne Greene, Pernell Roberts, Dan Blocker, and Michael Landon and later featured (at various times) Guy Williams, David Canary, Mitch Vogel, and Tim Matheson. The show is known for presenting pressing moral dilemmas.

In 1973, NBC licensed the distribution rights to the series, along with the rest of its pre-1973 library, to National Telefilm Associates, which changed its name to Republic Pictures in 1986. Republic would become part of the Spelling Entertainment organization in 1994 through Worldvision Enterprises. Select episodes ("The Best of Bonanza") were officially released in North America in 2003 on DVD through then-Republic video licensee Artisan Entertainment (which was later purchased by Lionsgate Home Entertainment). Republic (through CBS Television Distribution, which holds the television side of Republic's holdings) still retains the syndication distribution rights to the series. CBS Home Entertainment (under Paramount Home Media Distribution) is the official home video rights distributor at present.
