Sept. 7, 2012 -- intro: Just don't call them Trekkies.

Many fans of the original "Star Trek" series prefer to be called Trekkers, and they know everything about its intricacies.

From the shape-shifting creature featured in the first TV episode on Sept. 8, 1966, to the last episode on June 3, 1969, when Capt. James Tiberius Kirk loses his consciousness to a woman determined to kill him, "Star Trek" has taken its viewers "where no man has gone before" -- over and over and over again.
