Among fans of this cult classic it is called ST:TAS for short. This is the animated adventures of the crew of the USS Enterprise as they roam the galaxy in search of new worlds and new races. The show aired for two consecutive seasons on the NBC network beginning in 1973 and ending its run in 1974.

Each of the twenty two episodes are a half of an hour in length. This series was a joint venture between Paramount Productions and Filmation. Originally the idea was to have younger officers assigned to each of the important crew members. This could only be done if series creator Gene Roddenberry agreed to sign away creative control. He refused and instead made sure the animated series would continue to follow the plot lines and ideas he originally envisioned.

The show began on September 8, 1973 and was aired on Saturday morning's ensuring the time slot would be best suited for children. While it aired originally in the United States it was dubbed into many different languages allowing the episodes to air worldwide. The series also won a Daytime Emmy Award.

This series had two interesting and important things to note. One was the introduction of a holodeck. On the animated series it is known as the rec room but it is indeed the first such appearance of a holodeck of any kind. The other had to do with the space suit. In order to allow the characters to breathe outside the ship the animators decided to create a specialized suit that the characters would wear. This modified suit consisted of a belt drawn around the characters waist that created a yellow colored field around them.

Star Trek: The Animated Series is a series that is currently running and has 2 seasons (23 episodes). The series first aired on September 8, 1973.
