Girls Aloud are also notably one of the few British reality television acts to achieve continued success and longevity. According to "The Times", Girls Aloud are the highest-earning UK reality television stars, having amassed a fortune of £25 million by May 2009. The figure was increased to £30 million the following year, following Cheryl's appearance on "The X Factor". All five members were included in a 2010 list of Britain's richest stars under 30. Reviews of Girls Aloud's debut album noted the high quality of the album compared to output from other reality show contestants. In 2004, David Hooper of BBC Music exclaimed that "Girls Aloud are currently British pop royalty [...] in the ultra-fickle world of TV-generated pop, Girls Aloud have real staying power." Andrew Lynch of entertainment.ie said, "Girls Aloud really shouldn't have made it as far as a second album. [...] There's just one problem – the girls have a knack of coming up with utterly infectious pop songs".
