NebuAd

NebuAd was an American online advertising company. It was one of several companies developing behavioral targeting advertising systems, seeking deals with ISPs to enable them to analyze a customer's websurfing habits in order to provide them with more relevant, micro-targeted advertising.[3].

At one point, NebuAd had signed up more than 30 customers, mostly Internet access providers. Its agreements with providers covered 10% of the broadband users in the United States. Due to fallout following public and congressional concern, NebuAd's largest customers pulled out and NebuAd has shut down.
