It's a Friday night, the week's over, and you're curled up on the couch watching your favorite episode of "Haunted Golf Courses" when you notice that one of the characters is wearing a shirt you just really, really like. Without missing a beat or even pausing the show, you lift up your phone, snap a quick photo, and within seconds that same shirt's product page is on your phone. You see that the price is reasonable, and you really just want to grab it and return to watching your strange, niche TV show. You click "buy," select 2-day shipping, and return to watching the ghosts inhabiting the 4th hole at Boulder Creek. Shopping had been the last thing on your mind, and yet you just bought a product identified only by an image on another screen.
