Charter Communications has announced that it will no longer be attempting to target advertising based on user actions. The original strategy would have involved inspecting the contents of every packet sent or received by the customer. This usage pattern is associated with a specific IP and relevant ads are displayed on sites using NebuAd when that IP visits. NebuAd doesn’t directly share the IP, but we’ve seen in the past, even with obfuscation, a user’s search patterns alone have been known to give away their identity. The majority of all internet traffic is plaintext, but endusers have an expectation of privacy. User backlash is what eventually caused Charter to back down, but that doesn’t mean companies like NebuAd are going to be any less common.
