Time Warner Inc. (NYSE: TWX) is expected to report slightly higher third-quarter earnings against lower revenue Wednesday as floundering ratings at the embattled CNN were offset by a viewership boom at TBS and continued growth in affiliate fees for Turner Broadcasting. Additionally, the performance of Warner Bros. Pictures’ sole blockbuster for the quarter, “The Dark Knight Rises,” was only slightly hurt by the mass shooting at a midnight screening of the film in Aurora, Colo., on July 20.
