Imagine going into your local home improvement store with the goal of purchasing a new ceiling fan. As you walk through the entrance, a digital display changes from a general “Summer Closeout” message to an advertisement about a ceiling fan sale. What a coincidence, you think, chuckling to yourself. As you enter the lighting and ceiling fan department, a digital display in that area begins showing a commercial for the exact make and model of ceiling fan you’d researched before leaving your house. This is beyond coincidence, but you’re ecstatic to learn that the fan you want is on sale today.
