Dancing With The Stars and The Voice are once again facing off in a ratings battle. So which reality competition show will come out on top?

The ABC and NBC series have gone head to head for years. Last season, DWTS was the most-watched series on Monday nights for 10 weeks in a row, though The Voice frequently beat it in the coveted adults 18-49 demo.

THE 'DWTS' COUPLES ARE TAKING THINGS UP A NOTCH!

Last week was the first time the two shows went head to head this season. The Voice's premiere easily topped DWTS in the demo on Monday, 2.6 to 1.5. The Voice also won in total viewers by 1.2 million.

Both series have suffered ratings declines in recent seasons. Last May, each had its lowest-rated finale ever in the 18-49 demo. So they are both going all out to try to bring in viewers.

For The Voice, that means bringing in more big-name stars to serve as coaches. This season marks the Voice debut of Jennifer Hudson, who just won the UK version of the series. And next year, The Voice will welcome Kelly Clarkson to the panel.

For NBC, this had the added bonus of taking two potential judges away from ABC's American Idol revival, which premieres next year. Both women got their starts on the original Idol, and Clarkson was even in negotiations to join the new Idol as a judge. But NBC insisted this had nothing to do with its decision to bring Clarkson and Hudson aboard.

"We didn’t make the connection between them appearing on the show and ABC returning 'Idol,'" said the head of NBC's alternative and reality programming, Paul Telegdy. "We’re excited for them to join 'The Voice."'

Unlike The Voice, DWTS has kept its judging panel fairly steady since the first season. It relies more on the celebrity cast to draw in viewers. ABC went heavy on the sexy stars in Season 25 with celebrities like Nick Lachey, Nikki Bella and Terrell Owens. It also brought in stars with emotional backstories like Sasha Pieterse, Debbie Gibson and Victoria Arlen.

Of course, this is just the latest example of the ratings war between NBC and ABC. They also continue to face off in the mornings, with ABC's Good Morning America going head-to-head with NBC's Today. ABC famously tried to get an edge by moving Michael Strahan from Live to GMA, while NBC recently brought Megyn Kelly aboard in an attempt to boost viewership in the 9 a.m. hour.
