As the globe's most loved and loathed social media platform celebrates its 18th birthday, here are 18 fast facts about Facebook — courtesy of Search Engine Journal — that will guarantee to make you feel extra old today.

18 Facts You Probably Didn't Know About Facebook:

  1. Mark Zuckerberg originally only made Facebook available to students at his alma mater, Harvard University. (Okay, if you've watched The Social Network, you probably knew that one.)
  2. Facebook's color scheme is blue because Zuckerberg reportedly suffers from red-green colorblindness.
  3. Facebook engineer Andrew Bosworth said that designers pushed for an "awesome" button, but Zuckerberg ultimately vetoed the idea in 2007 and created the "like" button instead.
  4. Al Pacino was the first "face" on Facebook. The site initially displayed an image featuring a man's face disguised by pixels. It later came to light that the face belonged to the famed actor.
  5. Facebook users spend about an hour a day on the platform. The average user spends 58 minutes of their waking day on the service daily.
  6. We don't look at posts for long. We spend an average of 17 seconds on each bit of content.
  7. Usage on Facebook goes way up around 8 AM and 10 PM local time.
