Premise: Capt. Kirk, Mr. Spock, Dr. McCoy and the USS Enterprise crew seek out new civilizations in this seminal sci-fi series. The ship's five-year mission may have only lasted three seasons on NBC, but its impact has proved timeless. By the 1970s, its rabid fans---dubbed Trekkers---turned the show into a pop-culture phenomenon and syndication juggernaut that yielded a merchandising boom, a number of hit sequel and prequel spin-off TV series, a successful movie franchise and even a children's cartoon.
