Capitol's biggest-selling "imported" artist is The Beatles. When the Beatles had their first hits in England and Europe, Capitol Records did not want to market their recordings. Record producer George Martin turned instead to other American labels, trying to give the Beatles a hit record in America. Their records did not sell well in America at first, but "I Want to Hold Your Hand" became a hit through radio airplay of a British copy. Capitol Records changed their minds, released "I Want to Hold Your Hand", and it became a best-seller. Capitol then became the exclusive record label for the Beatles in America. When Universal Music sold Parlophone (the Beatles' British label) to Warner Music Group, Universal moved the Beatles' music to Capitol Records worldwide.
