If you’ve never been targeted by an ad because of your online behavior, then you’re probably just not paying much attention. According to an informal survey by the Interactive Advertising Bureau (IAB), more than 80% of advertising campaigns in 2009 involved tracking of some sort. The advertising business, in short, loves online tracking just about as much as privacy advocates hate it.

These third-parties – companies like Omniture, Double Click, AdBrite – can can combine online activity across the Web with offline data, creating detailed profiles and serving ads based on users’ behavior. As people increasingly use the Internet for health, financial, and other services, deeply personal information becomes available to advertisers.

Another reason to be concerned about behavioral tracking is the threat of inappropriate data collection by the government, which often gets private information about ordinary citizens from private companies. Limiting commercial tracking of our online activities may also help protect against this threat.

See the following video by Gary Kovacs where he explains the threats related to online privacy and how you are affected.
