Web stalking adverts

Internet cookies that sit in the background of your computer and then allow companies to push advertising to you as you navigate the Internet are scary to the informed and borderline witchcraft to the Internet novice. The latest EU legislation that has forced companies to be more open about their cookies policy doesn't seem to be working as all companies are doing is the bare minimum and then carrying on as before with banner advertising featuring throughout. Does this placed advertising enhance the customer experience and result in epic experiences?  Having more opportunity to buy something I looked at last week is useful if I had forgotten but for most of us that is not the case. Unusually this piece of legislation makes sense to me and stopping cookies that follow me round the Internet would lead to a more epic customer experience.
