I don’t understand what “traditional media” means in this context. Before the internet, kids didn’t have access to porn. It just wasn’t there when I was growing up. I’m sure someone out there had 8mm or 16mm porn films, but I as a child had no clue where to find those, and the physical stores selling them were not accessible: I didn’t have transportation to them, and they checked ID at the door. I heard of Playboy through friends at school, but I had zero access to it myself. I don’t think that was unusual.

Today every eight year old can browse Motherless for free with the same tablet he uses to watch whatever slop it is parents let their kids watch instead of educating them. That’s not a difference between “legacy” and “modern” porn but between zero access and full access.

The parent comment was talking about the other meaning of "media", the "news media". "Traditional media" then means newspapers, radio, and TV. As opposed to "new media" which is idiots yelling at each other on twitter or whatever.
