'Under The Dome' To End With Third Season – TVWise

CBS is closing the book on Under The Dome. The network has decided not to order a fourth season of the Summer drama series, TVWise has learned. The series finale will air on CBS on Thursday September 10th.
Per CBS, the series finale (which had originally been envisioned merely as a season finale) will provide closure for Under The Dome fans. In the series finale, when the Dome comes down, many questions about its origin and power will be answered, as two groups of residents engage in one final conflict that some won’t survive.
The decision to end the show is said to have been a creative one rather than being driven by ratings. The show was a hit when it debuted three-years ago with the series premiere pulling in just shy of 20 million viewers in live+7 delivery. Ratings have waned (somewhat considerably) over the last two years, but the unique financing model, which saw episodes made available on Amazon Prime the day after they air on the network, and strong international sales ensured that Under The Dome was still profitable for CBS.
“Two years ago, Under The Dome broke new ground in the summer and became an instant hit on CBS, as well as with viewers around the world,” said Nina Tassler, Chairman, CBS Entertainment. “Dome’s event storytelling and multi-platform business model paved the way for more original summer programming with the successful rollouts of Extant and Zoo. We’re excited to present the final chapter in Chester’s Mill as the story comes full circle, with the Dome coming down as dramatically as it went up.”
