CBS dominates Thursday night with growing comedies and steady dramas, while the shrinking Fox competition is out-rated by "Scandal" for the first time.

Starting the night off with a slightly resurgent episode of The Big Bang Theory, CBS topped Thursday with early returns from Nielsen, giving the network an average 2.7 rating among adults 18 to 49 and 12 million viewers over its three-hour block. Big Bang (4.6 adults), the night's top performer across networks, was up a tenth of a point from last week. Two and a Half Men (3.1 adults) rose four tenths of a point ahead of steady outings for Person of Interest (2.4 adults) and Elementary (2.0 adults).
