Clickz covers an EU rule that could have a huge effect in online advertising.

The amended directive will now state that national governments must “ensure that the storing of information, or the gaining of access to information already stored, in the terminal equipment of a subscriber or user is only allowed on condition that the subscriber or user concerned has given his/her consent, having been provided with clear and comprehensive information.”

Cookies without user consent would only be allowed when they are “strictly necessary” to provide a service “explicitly requested” by the user such as storing shopping cart information on e-commerce sites, for example.
