Below find a list of every major sci-fi television show we could think of that aired new episodes on American television between 2000 and 2024. If the shows started broadcasting prior to 2000, but still aired new episodes into the 2000s, they were still included. If shows continued past 2024, but started prior to that date, they were also included.

Note that we focused on live-action sci-fi shows; we will tackle animated sci-fi shows in a separate episode.
