>>96523749Teens only really became a demographic that businesses were interested in around the twenties.
So it went something like:
1920s - BMOC/Joe College/Jocks - Flappers
1930s - Not sure what to call them really; Andy Hardy types?
1940s - Zoot Suiters/Hepcats (Hipsters) - Bobby Soxers
1950s - Beatniks - Greasers - Teenyboppers
1960s - Yippies/Hippies
1970s - Disco King/Queen
1980s - Misunderstood Rebels/Surfers/Skateboarders - Valley Girls
A lot of those bled across decades though and I know I'm leaving out a bunch of them.
