TV Ratings: 'Dancing' and 'Mother' Return Down, 'Partners' Opens Low, 'Voice' Still Tops Monday

Increased competition from CBS comedies and ABC's Dancing With the Stars naturally shrunk The Voice's margin of victory, but the show (and a solid second outing of Revolution) still topped among adults 18-49.

Compared to last Monday, NBC's two-hour offering of The Voice was down just 11 percent to a 4.2 adults rating. The show also pulled in 11.9 million viewers, losing its audience crown to Dancing. At 10 p.m, the second outing of Revolution (4.1) retained a healthy ammount of ts record-breaking premiere for a 3.5 rating with adults 18-49 and topped its new competiton in Castle and Hawaii Five-0.
