On television, more often than not, two hearts are better than one.

It's true. As passionate viewers, we tend to fall in love with our favorite characters, and we really love it when they fall for each other. When the TV magic is totally working, we're rewarded with standout power couples -- dynamic duos that we root for and obsess over.

As Valentine's Day approaches, it's only fitting that we celebrate the small-screen pairings that have won our hearts. However, there are so many to choose from. You've got classic married sweethearts such as Cliff and Clair Huxtable ("The Cosby Show"), who were the epitome of warmth and grace. On the other hand, there are the iconic will-they-or-won't-they couples like Maddie and David ("Moonlighting"), who burned up the small screen with their sexual tension.

So, who rules? We're about to find out. We've created a blockbuster tournament that pits 32 of our favorite TV couples against each other in a series of single-elimination smackdowns. Think of it as March Madness, only a month early.

Best of all, you decide who wins. Here's how it works: Simply use the link at that bottom of this story to vote on the individual matchups. TV couples of the past, such as Ross and Rachel ("Friends") make up one side of the bracket. Present-day couples such as Mary and Matthew ("Downton Abbey") fill out the other.

By selecting your favorites -- with a simple click of the mouse -- you'll help us narrow the field. Of course, we'll want you to come back to vote again when the second round begins, and so on until a winner is chosen.

And now a word about how we chose the players: We limited the field to only couples who have been on TV since 1980. That's why you won't find Lucy and Ricky or Ozzie and Harriet in the competition.

We also went with faves who have solidly established themselves for at least a season. For example, as much as we love Jess and Nick on "New Girl," they need to pay their "dues" for a little while longer. They only recently shared their first kiss, after all.

That said, we realize that a lot of great TV couples aren't represented here, including Eric and Tami Taylor of "Friday Night Lights." So if there's a missing duo that is dear to your heart, let us know by leaving a comment and stating your case.

In the mean time, let's do our duty as passionate TV fans and get out the vote.
