A method and system to permit TV viewers to interact with program content broadcast over a subscriber network, such as cable, satellite, internet, or cellular telephone. The details of the ability for the viewer to interact is embedded as data in the program signal. The subscription provider broadcasts a visual indicator as a small icon during programming that informs the viewer that interaction is permitted. The viewer then uses a remote control to purchase products, vote on events, respond to polls, download files, request information, and request callback actions. The TV viewer uses the remote control to send information to a set-top box front-end application, and to iteratively create transactions that are batched and then sent to a back-end core application and database which then handles fulfillment.
