Some coworkers and I were talking about the Kentucky Derby over lunch the other day, a random topic that nobody in the group really was previously interested in. Nobody searched it or typed it into anything. Later that day my coworkers were seeing ads for the Kentucky Derby. Anecdotal, yes, but very creepy.
