The Twilight Zone is a science fiction television series that originally aired from 1959 to 1964. Its creator and narrator, Rod Serling, wrote most of the 156 episodes and used them as a tool to comment on social issues and explore the human condition in thought-provoking and metaphorical ways.
The show's format typically involved a standalone story that took place in a seemingly ordinary setting but quickly turned into a surreal and often unsettling experience for the main character. The themes explored varied from time travel, parallel universes, and extraterrestrial life to existentialism, morality, and the supernatural.
The Twilight Zone was groundbreaking in many regards, as it paved the way for other anthological science fiction shows and inspired multiple adaptations and spin-offs. Its legacy lives on, and the show's influence can be felt in modern TV series, films, and literature.
