I do, and the amount of money webmasters made back then was much better.
Some of the sites I ran got $10-$15 CPM. Ad campaigns targeted to my sites' niches could be up to $25 CPM.
Ever since Google introduced AdWords and its race to the bottom, content-heavy web sites are lucky to get 10¢ CPM.
But since the new kids on the block have never experienced a profitable web without tracking, they don't know any better and think it didn't exist.
