The Twilight Zone, the influential 1959-1964 science fiction anthology series created by Rod Serling, is now available to stream for free on Tubi. The show is widely regarded as one of the most influential properties in science fiction, shaping later works such as Black Mirror, The X-Files, Fringe and Lost, alongside films like Jordan Peele's Us, despite operating on a smaller scale than franchises such as Star Wars and Star Trek.

The series ran for five seasons on CBS, comprising 156 half-hour episodes (with a brief hour-long format in season four), and used science fiction and horror premises to explore deeper themes including prejudice, loneliness and morality. Serling hosted every episode and wrote nearly 100 of them himself, with contributions from noted writers Ray Bradbury and Richard Matheson producing classics such as "Nightmare at 20,000 Feet", "Dummy" and "To Serve Man". As an anthology, viewers can dip into standout episodes without following ongoing continuity, making it an accessible entry point despite some dated special effects.
