Having grown up through the early-ish days of the web, I'm still surprised the internet in general didn't get an 18+ age rating almost immediately.

Though I suppose that may have something to do with households in the early days having at most one internet connected device even if they were well off, so society could get away with blaming parents for not monitoring kids' use.

Don’t underestimate the impact of AOL - the main experience boomers and greatest generation had of the early internet was moderated and mediated. My parents were not on IRC.
