Another 80s early 90s information device was the magazine, there were tons of magazines which were mostly killed off by the Internet.
Social media is a whole lot of everything and 1% substance on a good day. It's a habit it's like Entertainment Tonight you sit there and one day think "why am I watching this?". That actually happened to me in the late 80s I realized I had a half smile grin Joker sort of thing watching banal celebrity news. These days instead of a dumb smile it's my left elbow with osteoarthritis from leaning on it reading about cats, rage faces and other memes or arguing with strangers over things 5000km away.
