TNT’s Rizzoli & Isles wrapped up its first season on Monday as the No. 1 ad-supported cable show of all time among viewers. The first season averaged 8.7 million viewers – a first for an ad-supported cable show. But the Angie Harmon starrer wasn’t the only series to post records for TNT: The Closer also finished its most-watched season ever on Monday with 8.4 million viewers. It now ranks as the No. 2 most-watched series of all time among viewers on ad-supported cable.

Last night’s finale of Rizzoli averaged 6.6 million while Closer lured 7.2 million. “TNT’s The Closer and Rizzoli & Isles have made this a summer to remember, from their record-breaking ratings to Kyra Sedgwick’s big night at the Emmys,” said Michael Wright, executive vice president and head of programming for TNT, TBS and Turner Classic Movies (TCM), in a statement.  “The Closer proved that a series in its sixth season can continue to reach entirely new creative levels while also building in audience.  Rizzoli & Isles brought two exciting new personalities to television and quickly established itself as a hit in its own right.  We are extremely proud of both series and the tremendous success they have enjoyed.”

Rizzoli’s July 12 premiere holds the record as cable’s most successful series launch of all time, with more than 9 million viewers, according to TNT.  The Aug. 9 episode currently ranks as ad-supported cable’s top scripted series telecast for the year-to-date, with 9.3 million viewers.
