No sci-fi show list is complete without "Dr. Who." The series started in 1963 and featured several men as the doctor - a time traveling, eccentric alien - and his comrades. Sure, many of the monsters were terribly cheesy, but it is a classic nonetheless. The show was canceled in 1989, made a brief return in a TV movie in 1996 and then was fully resurrected and came back into production in 2003. It continues today.
