> And it’s not as if anyone is clicking Google search ads for Coca-Cola and ordering a 6-pack right there. This is the same problem that these companies have with TV advertising.

Supermarkets already have a loyalty card program where you receive a small discount and in return you agree to receive targeted advertising based on your purchases.

Why don't these loyalty programs add a clause saying that they may also share your personal information with Google? That would mean Coca-Cola or Proctor and Gamble could see how much they spent on advertising to a particular person, and how much that person spent in buying the company's products.

Just some anecdata : AFAIK this is not allowed in The Netherlands. Retailers are not allowed to mine purchasing data on an individual level.
