Earlier quoted context omitted.
Since ads on the web are mostly produced by bots for bots, and distributed through shady borderline-criminal ad-networks I think we've already reached rock bottom years ago and it can only get better.
Wasn't that always true though? The earliest internet I knew was through AOL cd's, but it still seems like the internet as we know it was born of cancerous (mostly pornographic) ads.
