What are good examples of apps that have managed to monetize the precise location of millions of users in a way that isn't obvious (e.g. location-based advertising, or location-based filtering of social media content)? Collecting that data sounds creepy and nefarious, but if i think about what Experian and everyone else already knows about me, I don't know what information my phone's location would actually add that…
When “location” includes Bluetooth and wifi info, companies with a reason to invest can track your movement around a store to ~1m accuracy with BLE beacons etc. They know what you looked at in an aisle, for how long, and unless you paid in cash what you ended up buying via loyalty programs or credit card info. They also know, for each product you looked at and bought, or looked at and didn’t buy, what advertisements you were exposed to.
On an individual level who gives a shit, but with large enough datasets you can essentially A/B test your way to psychologically manipulating people into more sales.
