PageFair, a company that tries to help publishers show minimally intrusive ads that ad-blockers won't block, believes 198 million people actively use ad blockers.

That's why one online ad executive called the developer's approach a " ransom note."


It advocates non-pesky ads, and Adblock Plus users can set the browser extension not to block these "acceptable ads." But big publishers including Google that want Eyeo to sidestep this ad-blocking must pay Eyeo.
