Star Trek: The Original Series

Star Trek: The Original Series (or TOS) is an informal name for the television series Star Trek, that aired on NBC from 1966 to 1969, used to distinguish it from its sequel series, and from the larger Star Trek universe.

"TOS" chronicled the voyages of the starship Enterprise, under the command of Captain James T. Kirk. Seventy-nine episodes were produced, followed by an animated series (also called Star Trek, though commonly refered to as Star Trek: The Animated Series, or TAS), six feature films, and numerous novels, comics, and games.
