Back in July, TNT announced that The Closer would be back for a seventh season of 15 episodes. The series has been the top performer for the cable channel and the most-watched TV show on ad-supported cable television.

Now, TNT has announced The Closer is coming to an end. The press release notes that the decision came from series star Kyra Sedgwick.

Here’s the official press release…

TNT Announces Final Season of Landmark Hit THE CLOSER

TNT’s long-running, breakout hit THE CLOSER will wrap up its phenomenal run with a final season in 2011. The difficult decision to conclude the series with season seven was made by Kyra Sedgwick, the Emmy-winning star of THE CLOSER.

“It’s impossible to fully express our appreciation to Kyra Sedgwick, series creator James Duff and all of the other talented people who brought THE CLOSER to TNT viewers,” said Steve Koonin, president of Turner Entertainment Networks. “THE CLOSER was a pivotal series in setting a new course for TNT’s original programming, while also serving as a prime example of the storytelling strength possible on cable television.”

“I cannot fathom how difficult it will be to say goodbye to the incredible family we’ve created on THE CLOSER,” Sedgwick said. “I will always be grateful to James Duff for his love and friendship, as well as for creating such a rich and complex character who I have loved living with year after year. Mike, Greer, Rick and all of our outstanding cast and crew are forever in my heart. I want to thank TNT and Warner Bros. Television, as well as the incredible fans of THE CLOSER, for all of their unwavering support over the last seven years.”

THE CLOSER proved to be a resounding success after its debut on TNT in 2005. The series – which is produced for TNT by The Shephard/Robin Company, in association with Warner Bros. Television – was created by Duff, who serves as executive producer with Greer Shephard, Michael M. Robin, Rick Wallace and Sedgwick. In its seventh and final season in 2011, THE CLOSER will reach its 100th episode. Production of the 15-episode season will start in spring 2011.

“Kyra Sedgwick has distinguished herself not only as an extraordinary actress, but as a remarkable set leader and presence on THE CLOSER,” said Peter Roth, president of Warner Bros. Television. “The series has literally changed the face and course of both TNT and Warner Bros. Television, and we will always be grateful for all that she has contributed toward that success.”

“Kyra blazed a new trail in the television landscape with her performance as Brenda Leigh Johnson,” said Michael Wright, executive vice president and head of programming for TNT, TBS and Turner Classic Movies (TCM). “Like her many fans, we will miss her terribly, and we will be forever grateful for the time we got to spend with her.”

THE CLOSER is currently in the midst of concluding its sixth season. This past summer, the series was the foundation of TNT’s strong Monday night lineup, which featured the introduction of the new hit series Rizzoli & Isles.

THE CLOSER and Rizzoli & Isles currently rank as basic cable’s top two series of all time. In 2010, both series averaged more than 8 million viewers, marking a first for a basic cable network. THE CLOSER also kept up the pace by growing its deliveries compared to season five.
