The Beatles. They were bigger than Jesus because they could combine pop music and rock music to create a boppity enough sound for the hipsters of the 60's, as well as a wholesome enough sound for the conservative Midwestern people of the 60's.
The Beatles had the most No. 1 albums in both the UK and US, with 15 in the UK and 20 in the US. They also had dozens of No. 1 albums in other countries, such as Germany, Finland, Australia, and Canada.

Among all of this, next time you go to the Mall, see how many Beatles shirts you can find. Look for all the merchandise that was created from it.
Even after the Beatles split up, each individual Beatles had a phenomenal musical career. Paul McCartney's Wings, John Lennon's solo career, George Harrison's huge benefit stuff, like Concert for Bangladesh, and Ringo Starr's solo career.
