In the late 80s and 90s, supermodels were the top models that were models plus spokespersons or other occupations.
In 2020, a model is anyone with an instagram account and a supermodel is anyone who has actually had a paid modeling gig.
Ah, those were the days when supermodels were beautiful women (Heidi Klum, Tyra Banks, et al) who posed in Victoria's Secret in their underwear.
