Factual error: Samuel Clemens, who has written several humorous tales for the Territorial Enterprise, tells the publisher he would like to start writing serious news stories. The publisher replies, "This is a newspaper, not a comic strip. You write it and I'll print it." The first comic strip, "The Little Bears," debuted in 1893 and the term "comic strip" did not enter the vocabulary until 1920. "Bonanza" is set in the 1860s.
Factual error: The show is set in the 1860s. However, in several episodes, trail boss Gil Favor can be seen wearing Wrangler jeans. The Wrangler brand was not introduced until 1947.
