^* “Retargeting” is ads-speak for the practice of showing a user ads based on what he or she has browsed on the Web. At its simplest, it’s the creepy tactic of showing you an ad for a product you just eyed on Amazon or other online commerce site. At the time of the meeting described here, the targeting was more sophisticated than merely showing you a version of a product you’ve already seen, but the term was really code for predicating your experience on site A with things you’ve done on sites B, C, and D (and perhaps even done offline, in physical stores).
