You can see indirect evidence for this by looking at the exponential rise in ad-blocker-blocking efforts from a wide array of sites. 'Hi, we see you're using an ad blocker. Please turn it off.' That literally did not exist several years ago, even though ad blocking has been around for decades. Companies in recent years are getting aggressively desperate as the web becomes increasingly user friendly. At the same time, mobile is still dominated by an OS developed by the the world's largest ad delivery corporation - and it behaves accordingly.

What is "several years"? This has definitely existed, say, five years ago. Not at this scale, of course, but it's not a recent invention by a long shot.
