Under the Dome is an American science-fiction mystery drama television series. It premiered on CBS on June 24, 2013, and concluded on September 10, 2015. The series was developed by Brian K. Vaughan and based on the novel of the same name by Stephen King.
Under the Dome tells the story of the residents of the fictional small town of Chester's Mill, when a massive, transparent, indestructible dome suddenly cuts them off from the rest of the world. Military forces, the government, and the media positioned outside the barrier attempt to break it down, while the residents trapped inside must find their own ways to survive with diminishing resources and rising tensions. A small group of people inside the dome must also unravel complicated mysteries to figure out what the dome is, where it came from, and when (and if) it will go away.
Under the Dome was an instant success for the network; the premiere in June 2013 broke the record as the most-watched summer drama premiere on any television network since 1992. The show continued to enjoy high viewership ratings throughout its first season, but the second and third seasons of the series had significant declines in live viewership. Initially, Under the Dome had a positive critical reception, which changed into mixed reviews as the series progressed.
Under the Dome came to a conclusion in September 2015. Over three seasons, 39 episodes were produced. Executive producer and showrunner Neal Baer stated in an interview after the finale aired: "I'm very happy with this ending. I feel very satisfied. We made it so there could be another [season]… but it wasn't necessary."
