After the cancellation of the original Star Trek TV series in 1969,network executives over at NBC came up with one of the most innovative and one of the best 'Star Trek' series ever. Even though it ran on Saturday Mornings,and was aimed directly at children,the series wasn't able to do what it precessdor would have in the original,but it had a whole lot more going than it expected being the first ever to have its own cartoon show,but also have the same cast from the original show to do the voiceovers. The animated was excellent throughout,and since it had interesting stories that went along with it,the show won several awards including two Peabody Awards during its two year run on the NBC network(from 1973-1975).
If you do catch some of episodes there are some good ones out on video that are worth seeing,including the part where Lieutenant Uhura commands the ship when Captain Kirk and Mister Spock faced great danger on a hostile planet. It may have been forgotten,but it still holds up to this day and as one of the best animated science-fiction shows ever devised for Saturday Mornings. Re-runs are out there somewhere.
