"M*A*S*H" remains one of the most popular TV shows ever. Although the 1970s-era show was about the tragic Korean War, it made you laugh, cry and think. But how much do you know about this perennial favorite?

"M*A*S*H" was filmed in two locations: the former Fox Ranch at California's Malibu Creek State Park, and 20th Century Fox's Studio 9. Although most of the original characters left the show during its 11-year run, that never harmed "M*A*S*H's" popularity. After all, people serving in the military during wartime do come and go, according to the terms of their deployments. So that seemed realistic.

You may know, or at least suspect, that "M*A*S*H" and its actors won numerous awards over the years. But did you know that the Smithsonian accepted two complete show sets from 20th Century Fox? The Washington, D.C., museum normally doesn't accept complete television sets — only representative props. But it now has "M*A*S*H's" operating room and the "Swamp" in its possession, the latter being another name for the bachelor officers' quarters.

Interestingly, "M*A*S*H" didn't do so well in its inaugural year; it was actually in danger of being cancelled. Luckily for us, it was given a second chance, after which it hit the top 10 in viewer ratings. It remained popular from that second season on, until its end in 1983.
