It hasn’t been since NSYNC, Backstreet Boys and 98 Degrees first dominated the pop charts more than a decade ago that we’ve seen such a surge of guy group domination ? that is until now.

From The Wanted joining forces with Justin Bieber to the Jonas Brothers’ reunion show, it’s safe to say that boy bands are back in a big way. And there’s no question that leading the pack is “X Factor” U.K. alums One Direction.

In 2012, Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson took the U.S. (and world) by storm ? dropping two #1 albums, selling out Madison Square Garden in 10 minutes, winning three Video Music Awards, and taking the title as MTV’s Best Artist of the Year.

“We’ve had a big year,” Malik told MTV News when accepting MTV’s year-end award.

And with so many milestones in 2012, the fivesome had a hard time pinpointing just one moment as their favorite.

“I think it’s always a really hard question when we get asked our top moment,” Styles explained. “Madison Square Garden was definitely one of the top things we’ve ever done and will ever do. I think it just topped off an amazing year for us, and it’s just been amazing.”

Another unforgettable accomplishment for 1D was at the 2012 MTV Video Music Awards. Not only did the guys perform their smash hit “One Thing,” but they took home the Moonman for Most Share-Worthy Video, Best Pop Video and Best New Artist. Plus, how could we forget: Horan snagged a kiss from Katy Perry. “The VMAs [were] unbelievable,” Styles recalled.
