There is an advertising ecosystem which never seems to get mentioned in these threads.
Because I think that ecosystem - sans AdSense - is all tried, I should think by many if not most webmasters of yore, and concluded not worth the time/effort it requires to maintain it. Unless you have a team of ad-execs working for you.
There is still nothing remotely close to AdSense for the amount of return against the minuscule time/effort required to run it (just dropping a few lines of silly code on your webpage) while freeing up time/effort for one to run and enjoy their sites, not micro/macro manage their monetisation, IMO.
