The '90s teen pop boy band followed a well-crafted formula. First, we had the boy band archetypes: the dreamboat; the baby-faced, sweet boy next door; the bad boy; the eccentric one; the goofball; the quiet one; the sensitive one; and the older brother type. HA! Every successful boy band and even R&B male vocal groups followed a combination of these archetypes.

Each boy band also had to have the right sound, look, and moves. We are talking bubblegum pop tunes marketed to teen demographics and smooth ballads that made your heart melt. Dance moves inspired by the King of Pop. Outrageous threads that were in unison, but showed off each individual members' physique (heck, sometimes open shirts or no shirts at all). And don't forget about the hair.

All of these elements led to screaming and adoring female fans. It was magic—but no other groups captured that magic the way NSYNC and Backstreet Boys did.
