One reality competition veteran began its season last night as another ended its latest one. ABC’s Dancing With The Stars (3.1/8) returned for Season 16 with a two-hour debut Monday as The Biggest Loser (2.6/7) wrapped up its 14th cycle. Coming off record lows and double-digit declines a season ago, DWTS is hoping to pull out all the stops to find its footing. (One such attempt was the addition of The Bachelor star Sean Lowe last week to this year’s celeb contestants.) DWTS also didn’t have to face NBC’s The Voice like it did for last spring’s season premiere. The dance series’ season debut last night was up 24% over its Season 15 premiere on September 24, making it the highest-rated show of the night among adults 18-49 and the most-watched show overall with 16.76 million viewers. However, head-to-head with Biggest Loser and CBS’ comedy lineup, DWTS was down 11% from last year’s Season 14 premiere on March 19, marking the lowest spring debut ever for the long-running series. And the landscape will change even more next week when ratings heavyweight The Voice and the J.J. Abrams-produced Revolution return to NBC.
