Amazon has been around for 23 years now (Amazon Prime for 12 years). People have been heavily using Amazon daily for online retail and wishlists for over a decade. For most people I know, they've been the go-to place for most Christmas and birthday shopping for years. They're terrible at recommendations--they're the best case scenario. Google and other advertisers are worse. No matter how much information they have, they're just awful. There's also distrust between ad networks, advertisers, and users. So even if they collect all this deep information, you can't trust the other group to be telling you the truth to the other group. I would love a scenario where I get personalized matches for my needs even if that means me handing over more info. Podcasts seem to be the only place where they're a) big enough to get direct sponsorship but b) small enough that the sponsors are still relevant...and they're using the same techniques as traditional media like TV/radio.
