If you have people who find a blog post of yours, and then get drown by hundreds of ads floating around the screen, you're only inviting people to install an adblocker.
Setting up even more ads will not make you earn more money, the exact opposite effect will happen.
Because most of your visitors don't block ads because they don't want you to earn a little bit of money (commies do, but they're the types of people who will say "money evil" while hoarding as much money as possible for themselves), many don't want to be spied on, but that's only a tiny percentage of adblocker users.
The reason why vast majority of the people who use adblockers is exactly because there are way too many ads, and they're just annoyed by the ad spam, their flashiness, how they slow down computers, and so on.
@ryo Linux Mint does it, but it's for laptops that already have their OS pre-installed, so it might as well be their own product, even though they're from ThinkPenguin.
There was also a website I visited a lot back in high school which I used for cliffnotes on reading assignments. They had a sponsorship deal with the Nook (an e-reader device similar to the Amazon Kindle). It was just a simple plain text ad.
And a lot of imageboards have their own self-hosted ads that aren't targeted, but that's because most ad companies don't want to deal with those types of sites.

Not that many have facial recognition. A lot of them still don't even have audio. I know there are advanced CCTV cameras out there now, but you'd be surprise how many of them are old-school.
Still good enough to estimate how many people saw the ad.
@ryo If you only care about the number of views from that ad, and the ad is a static image you can see how many unique clients accessed that image in the server logs.
Just like how offline ads work.
But it's untrackable, so advertisers (or PR departments) won't do that.
