There’s zero doubt that “Seinfeld” is one of the most beloved sitcoms ever made.
Per IMDb, the NBC show followed “The continuing misadventures of neurotic New York City stand-up comedian Jerry Seinfeld and his equally neurotic New York City friends.”
The show had an intimate four-strong core cast. It starred Jerry Seinfeld as himself, with his friends George Costanza, Elaine Benes, and Cosmo Kramer played by Jason Alexander, Julia Louis-Dreyfus, and Michael Richards, respectively.
It aired for nine seasons and 180 episodes from 1989 until 1998. That means it’s been 28 years since it went off the air.
With that in mind, wouldn’t it be fun to directly see how the core cast looked back then compared to today? Let’s do that now…

We wish them well with their ongoing careers.
