Both Outdoors and Television do the same by-demographic buying/selling, in fact, that's where the Internet got it! Outdoors and Television don't track (except when they do[1]) because they don't need to; because there exists a huge problem with digital that doesn't exist for Outdoors and Television: Ad Fraud.
There are a lot of websites out there with a lot of (aggregate) traffic, but that individually don't have enough traffic to approach advertisers directly. It is good that we can monetise them because sometimes this can fund their niche content, however it also means that people can make fake websites and trick advertisers into buying that space.
Of course, real users don't go to those sites, which is a nascent use for tracking: Sites that are visited by some population who don't visit other sites are simply more suspicious.

Yes to both, but I am suspicious about most of the mathematics used to prove uplift and conversions using micro-models because of simple counter-examples like the blank ad[1] that generated a median clickthrough rate, and because of the prevalence of one-tailed "dropoff" charts don't pass the laugh test.
For more on this phenomenon, there's a book[2] that I'm oft to recommend.
Nevertheless, I also believe there are genuine means for revenue that utilise user tracking, but this is more work and attention than the typical digital ad campaign receives.
