But they weren't the first to appeal to teeny boppers that phenomenon was around before and each generation had it's own teen idol. Before The Beatles it was the Bobby era (Bobby Vee, Bobby Vinton) and before that it was Elvis girls were screaming at and before him it was Frank Sinatr

Boy Bands in reference to The Beatles is an anachronism, boy bands started in the late 70's early 80's long after the Beatles and are based on R&B vocal groups more than Rock Bands. Another difference is that The Beatles were a band before they were discover, and Boy Bands are corporate construct pieced together by a producer etc.
