UPDATE 11:30AM: TNT’s new original series Rizzoli & Isles drew some 7.6 million viewers for its premiere last night to rank as the most watched ad-supported cable series launch of all time with commercials. (Overall, it is close second to the commercial-free 2008 debut of the now-defunct TNT legal drama Raising the Bar, which attracted 7.7 million viewers.) The series, starring Angie Harmon and Sasha Alexander, held onto almost 100% of its lead-in, the sixth-season premiere of The Closer, which delivered an also impressive 7.7 million viewers, up 7% over its fifth-season premiere last June. That means that TNT may have found a perfect companion for the Kyra Sedgwick-starring drama, with the two shows lifting each other up. Rizzoli & Isles built on its lead-in from The Closer among key adult demos, with 2.1 million adults 18-49 and 2.7 million adults 25-54.
 Lorraine Bracco co-stars on the Warner Horizon series based on Tess Gerritsen’s novels.

PREVIOUS 7:20AM: Total viewer numbers won’t be available until later today, but in the overnight ratings, TNT’s new drama Rizzoli & Isles scored a 5.6 national rating. The procedural starring Angie Harmon and Sasha Alexander held onto 100% of its lead-in, the season premiere of TNT’s flagship drama The Closer (5.6), which rarely happens. There was also a nice bump for the veteran drama starring Kyra Sedgwick, which scored a 4.6 rating for its season premiere last summer. As for the shows’ audience, it should be pretty big – when The Closer opened with a 4.6 rating last year, it translated to 7.1 million viewers.
