You mean, by spamming you every ten minutes with random ads between crappy shows? The premium content (Netflix, HBO, Hulu...), people are willing to pay for it.
It's the same trade-off for the web: if you want good content, either you pay for it (NYTimes), or you have to deal with targeted ads.
TV networks don't target ads not because they don't want and prefer their own business model. They don't do it because they can't.
And anyway: targeted ads are also way better for the user experience. If the advertiser know you're blind, it won't show you 1000 times an ad for sunglasses.
Tracking and ad targeting mean less ads across the web.
Most ads are not malicious content at all. Wake up, the web has changed in 15 years. And like it or not, the whole web economy is based on advertising. Do you prefer to be charged 5 cents for every query on Google?
