  • Millennials are people born between 1981 and 1997 who are between 21 and 37 years old in 2018.
  • Many millennials aren’t familiar with some of the technological and cultural relics from earlier eras.
  • For instance, most millennials probably aren’t familiar with Brownie cameras, sea monkeys, or ‘H.R. Pufnstuf.’

You can bet most millennials have heard of Snapchat, emojis, AirPods, and Drake.

But sea monkeys, Brownie cameras, milk chutes, and Ricky Nelson?

Not so much.

The Pew Research Center defines millennials as those who are between 21 and 37 years old in 2018, on the cusp of Generation X (and including the youngest “Xennials“) and followed by Generation Z. They’re the largest generation so far, and they influence everything from fashion trends to office layouts.

But they don’t know everything.

Below, find 23 things that for many people are fond memories — but for millennials, they’re almost unheard of.
