English-Irish teen-pop boy band formed during the British TV singing competition "The X Factor" in 2010. They finished third in the series and subsequently signed with Simon Cowell's label Syco Music. In November 2011 they released their debut album "Up All Night". The album went straight to number one on the US Billboard 200 chart, which made One Direction the first UK group in US chart history to debut at number one with their first album. Propelled to international success by social media, One Direction's four albums, Up All Night (2011), Take Me Home (2012), Midnight Memories (2013) and Four (2014) topped charts in most major markets, and generated hit singles including "What Makes You Beautiful", "Live While We're Young", "Story of My Life" and "Night Changes".
