This next wave is already here and has been for years / decades. It's social media, where people post their experiences, products, things they watch, things they play all the time. And some of these people will get paid for posting things. Some of these people aren't real people. Some of these posts will get promoted, either with direct money or through bought upvotes.
See also the "fake news" pandemic now almost 10 years ago, where they weaponised these techniques towards steering voting behaviour in favor of right-wing politicians.
But browse Facebook (or remember when you did); at least on my side, pretty much all posts from humans (in between the ads) was them sharing what / where they were eating, where they were going on vacation, what they were watching / playing, etc. It's word-of-mouth advertising disguised as possibly shared interests.
