The nineties was an eclectic period of music history, with the emergence of grunge and Britpop, and the continued growth of urban music and hip-hop. But one genre undoubtedly dominated the UK charts from 1990-1999, where nine out of ten artists who spent the most weeks at number one were pop groups or pop acts, and 12 out of 14 of artists with the most number ones in that decade hailed from the same category. Pop music, not to be confused with the sixties-punk sound inherited by Britpop, was a force to be reckoned with.
