It befuddles me to see that there so little pushback against the use of these types of tech. We can't trust advertisers to limit themselves. They are only limited by what current technology can achieve but the goal posts keep moving and so is their appetite for more intrusive ways to gather data. There is a strong competitive incentive for them to build a system capable of proving that a specific consumer seeing a specific ad ended up in a specific sale. Imagine how much value that information could have to a company wanting to sell its products! Near-guaranteed sales, ad expenses laser-targetted to those who will actually buy! A boon for both advertisers and sellers! Advertisers gather and cross-reference public information, credit information, track people tastes, political affiliations, phone location, where they go, what they look at... all to present consumers with hyper targeted adverts that result in more sales. The more detailed and precise the data, the more targeted the ad and the higher the chances of persuading a customer to part with their money. Removing uncertainty is the goal. I sincerely hope that these overreaching applications of what is basically surveillance tech meet stronger resistance. Legal challenges are best, but some old-fashioned 'guerilla' tactics may also be effective... I wouldn't be sorry for companies like Clear Channel either way.
