Fall has traditionally been the season for major TV premieres, and 2021's autumn TV slate is no exception. The rise of cable and streaming have meant that new series debut year-round, but fall offers a unique combination of pilots from the traditional broadcast networks and significant offerings from other platforms. In particular, the fall months are slated to see some long-anticipated sci-fi and horror projects arrive.

The start of the 2021-22 season sees TV getting back to some kind of normalcy after the COVID-19 pandemic forced major disruptions to filming schedules. Network shows like Supergirl that ended mid-season.
