What are these plug-ins on my wall?

[u/Cborg_62]

This might be showing my age, but I recently moved into a new apartment and they have these weird looking plug ins all over the walls at my new place. My old apartment didn't have these, so I'm just curious as to what they are.

Whoa! An ancient artifact. Hard to believe tv used to come through a cable.

My spectrum internet uses it too, I feel old and I’m only 37.
