A remote control that tunes an appliance, such as a television or a radio, can scan marks on physical media, such as barcodes on products, publications, and print media. The remote control can present a user with a question regarding advertising content on a physical medium to immerse the user in such advertising content. The user can receive a reward, such as a coupon for a discounted purchase, for correctly answering the question. The remote control can generate a shopping list by scanning and identifying products that a consumer or household consumes. A remote server that is affiliated with a particular manufacturer or distributor can maintain the shopping list as a consumer service. The shopping list service can be a vehicle for promoting product brands associated with the manufacturer or distributor.
