Yep. I'm a Mickey Mouse fan, and was talking to a coworker about Disney and wanting to do a Disney Cruise, and within minutes was getting ads for Disney Cruise Lines. Same experience after taking to my wife about the pros and cons of getting a Mercedes; ads for Mercedes started appearing, not just on FB, but on random web sites too. It's fascinating and scary all at once.

Watch the follow up. This test is flawed, as he was saying those things into YouTube, a Google product, with live-captioning/transcription enabled, therefore tailoring his ad profile based on the content indexed from his stream.

It's still scary how quickly Google is able to go from voice to advertisement, though.
