How many seasons did The Sarah Connor Chronicles run?

The Sarah Connor Chronicles ran for two seasons.

The television series premiered in January 2008 and continued with a second season that began later that year. It follows Sarah Connor, her teenage son John, and the Terminator known as Cameron as they attempt to prevent the rise of Skynet and survive threats from both humans and machines.

Lena Headey played Sarah Connor, Thomas Dekker played John Connor, and Summer Glau portrayed Cameron. The series served as a continuation of the events of Terminator 2: Judgment Day while using its own timeline and introducing new characters and storylines.

The show was canceled after its second season, so it ended without reaching a planned third season. It is sometimes confused with the Terminator films or with a limited miniseries, but it was a broadcast television drama with 31 episodes across its two seasons.
