According to the website of ''The New Grove Dictionary of Music and Musicians'', the term "pop music" originated in Britain in the mid-1950s to describe rock and roll's fusion with the "new youth music". ''The Oxford Dictionary of Music'' states that artists such as The Beatles and The Rolling Stones drove pop music to the forefront of popular music in the early 1960s. In the following years, Britain widely occupied a part in the development of rock music, with British acts pioneering hard rock; raga rock; art rock; heavy metal; space rock; glam rock; new wave; Gothic rock, and ska punk. In addition, British acts developed progressive rock; psychedelic rock; and punk rock. Besides rock music, British acts also developed neo soul and created dubstep.
