When One Direction's show this weekend at the Palace went on sale a year ago -- right after the British group's performance at Detroit's Fox Theatre -- they sold out instantly, and it's remained the hardest concert ticket to get so far this year. How'd these guys get to hot? Here are five key points to know about the group's rise...
* One Direction was formed during the summer of 2010 audition "boot camp" for the British version of "The X Factor" at the suggestion of judge Nicole Scherzinger. One Direction finished third in the competition, but "The X Factor" creator Simon Cowell signed the group to his Syco Music label, scoring an immediate British No. 1 hit and a Billboard Top 5 with "What Makes You Beautiful."
* The group has released studio two albums -- "Up All Night" (2011) and "Take Me Home" (2012), which both hit No. 1 on the Billboard 200 and went platinum. "Up All Night" was the fist debut album by a British group to accomplish that feat. One Direction has sold more than three million albums and eight million singles worldwide. Its third album, "Where We Are" is due later this year, and a stadium tour is already set to start during April of 2014.
* The authorized book "One Direction: Forever Young" was published in February of 2011 and became an immediate best-seller. A 3D film, "One Direction: This Is Us," directed by Academy Award nominee Morgan Spurlock, opens August 30.
* The group's Harry Styles, 19, was romantically linked, briefly, to Taylor Swift -- which means she'll probably write a song about him for her next album. -- Gary Graff
