I'm not quite sure. Probably because "Hanky Panky" and "I Think We're Alone Now" had more to do with it than anything else. For some reason, staccato eighth notes on a bass sounded like bubblegum. Basically, groups like the 1910 Fruitgum Co. took my early format and kind of perverted it, and made these mindless pre-fab hits over and over. In the 60s, anybody who was making commercial music, that is music that didn't have a political slant to it, or wasn't taking drugs, was bubblegum. And that term kind of hung on a lot of people back then, and it's unfortunate.
