I dunno, I’ve been doing some genealogy research and looking at a lot of newspapers from the 1800’s. It’s striking to me how much they are essentially Facebook. Sure, on the front page there’s the news of the day, but on the inside are jokes, riddles, local notes on who visited who and where. And the ads. Literal snake oil! As well as all sorts of other sketchy tonics for curing any sort of “ill constitution”.

I think those of us on this forum likely grew up in a golden age of ads being relatively harmless, but I’m not sure that’s the normal state.

It's not the "state of nature", but there's obviously been a lot of litigation and regulation in the meantime. Look up the charmingly named Carbolic Smoke Ball case, for example.
