Targeted ads are everywhere. Do one Google search for a new guitar, and all you see are guitar ads for the next few weeks. It may not even matter if you bought the guitar. Your browsing history allows Google to create targeted ads specifically for you, based on your searches and interests. If you've accepted that this is how it works and how it will always work, you may be stunned to learn that Google has said it will stop the practice. As has been noted, this is being done even though targeted ads are a core part of the search giant's business model. This move could change online advertising forever.
