Musically, each band was the most successful in a different genre within 'rock', 'beat' and 'blues-based'.

Culturally, the Beatles really did change the world. Without their other-worldly talent (along with George Martin), coupled with their personalities, Western culture--and the rest of the world with it--would have taken a very different path. The Rolling Stones were one of the pebbles being pushed along by the flow.
