With its primetime lineup finally back in the hands of Time Warner Cable customers in New York, Los Angeles and Dallas, CBS won its first night back from the monthlong blackout with a small boost for Under the Dome. Though the carriage dispute never had a noticeable impact on the network's ratings, Under the Dome was nonetheless up on Labor Day, posting a 2.6 rating among adults 18-49 according to Fast National returns -- an improvement of one-tenth of a point from last week.
