In my experience, it's because internet advertising is indeed globally horrible, but advertising on internet is often not about global effects.

To give you a perspective, efficient "performance" (the kind which wants you to buy now) advertising is a click ratio of about half a percent on ads, which vastly outperforms the basic performance one, usually having a ratio of about a tenth of a percent. Of those fractions of a percent, a fraction of a percent will actually buy...

That still means ads missed the target 995 times out of 1000, so are still globally horrible.

Nevertheless, since ads on the internet are so cheap (prices are often negotiated by 1000 ads, to make it a bit more tangible, and we're talking like 5$ per 1000 ads here), it's still sometimes worth it.

So yeah, the global experience is crap, but that's often not the point anyway.
