CBS has put all 79 episodes from the 3 seasons of Star Trek: The Original Series online at for you to watch for free. There are commercials, of course, but that’s a small price to pay for access to every episode of Star Trek online so that you can watch them wherever you are.

Screenshot of the free Star Trek episode player online is also letting viewers watch all 92 episodes and 4 seasons of Star Trek: Enterprise for free as well, and has clips and features from all the different Star Trek series.
