One Direction's Niall Horan said they felt "like the Beatles" as the band celebrated becoming the first UK pop group to debut at number one on the US album chart.
Their first release Up All Night has rocketed into the top spot on the Billboard chart.
The boy band - Niall, Harry Styles, Zayn Malik, Liam Payne and Louis Tomlinson - was formed by TV's The X Factor and signed to Simon Cowell's label Syco.
Niall, speaking from the US, credited social networking at the key to helping their success.
"When we started out, we thought we would do an album or two and then hit the world, but YouTube came into play and spread the word worldwide. More people know about us everyday. The power of the internet is amazing", he said.
"It's like The Beatles, who spread the word around the world through radios and TVs in the 60s."
Niall said it was strange to think that One Direction had achieved something that had eluded so many great bands of the past.
"I'm lost for words. When we heard that we were the first British band to get the number one debut album in the States in history, you think of names like The Beatles, the Stones, Spice Girls.
"It's absolutely amazing to be put up there with those names. Bruce Springsteen has been number one for the past week, and Adele before that. It's amazing to be put up on the top of the charts with those people. We had a battle for the No 1 with Adele, and it's been amazing to come up on top."
