Some of that 'offline' pervasive tracking you describe does exist! Not on the scale of the internet and you give some good examples that are egregious. a lot of it is just 'adtech' bs, but it's there. and the traditional in-store transaction data marketplace is huge. Companies have been tracking you and your purchases around forever. passive bluetooth IDs track you in store - though didn't iOS mitigate that by changing them frequently? idk maybe not. There are some 'eye tracking' billboard tech but it's kind of dumb imho. The simpler is just trying to estimate impressions. though maybe that's more digital ads than not. but collecting, selling, aggregating consumer data, combining it with purchase data, and using that for direct marketing ha been around for ages.
