One Direction
Probably one of the first names that come to mind when one thinks of reality show successes. Although given that the band members each seem to be pursuing a solo career for the time being, it appears, although fans are praying for otherwise, that this group could be over. However during their tenure together the five guys Harry Styles, Niall Horan, Louis Tomlinson, Zayn Malik, and Liam Payne, who put together in a group during the UK version of the X Factor in 2010 by judges Simon Cowell and Nicole Scherzinger, delivered plenty of hit songs like Best Song Ever, Story of my Life and Half a Heart.
