A couple of years ago I read an NBC article[1] about low-quality, spammy ads on the Web. The article was decidedly negative about them....and yet (at least at the time) the page was full of them: "Billionaire prepares for financial ruin" etc, all the AdBlade/Taboola-type shit. It was pretty ridiculous, given that the tone of the article from the very beginning was positively railing against low-quality ads.
