TV Ratings: 'Under the Dome' Returns Down But Dominant

Last summer's CBS scripted breakout suffers a sophomore drop, though it easily tops all other broadcast competition for the night.

CBS went back Under the Dome on Monday night. While last summer’s breakout hit did shed much of its viewership from its series premiere, it's still the biggest scripted outing to hit the broadcast nets so far this summer.

At 10 p.m., the episode averaged a 2.2 rating among adults 18-49 and 9.4 million viewers. Off from last summer's massive 3.3-rated debut, Dome did end up a bigger performer with time-shifting. Its weekly demo haul grew by an average of 44 percent last summer. Still, Monday's return was within a tenth of a point of its series low.

Under the Dome bested its broadcast competition for the night, which included The Bachelorette, MasterChef and 24: Live Another Day.

As for its competition, most Monday programs were on par with last week. On Fox, MasterChef (1.9 adults) was up two-tenths of a point before a steady 24 (1.5 adults). And on ABC, both The Bachelorette (1.5 adults) and Mistresses (1.1 adults) held even with previous outings.

NBC special Harry Potter: The Making of Diagon Alley pulled a 0.8 rating, and Beauty and the Beast (0.3 adults) was even on the CW.
