A television viewer is automatically connected over a telephone network to an information service associated with or related to the television program being viewed. A control unit produces a control signal in response to a viewer actuated button. Data encoded in a non-visual part of the television signal is recovered by a decoder. An automatic dialer connects to the network and dials a telephone number in response to the viewer actuated button being pressed. A communication control system relays information between the information service connected to over the telephone network and the viewer. The communication between the information service and the viewer may be voice and/or data communication, with text data being displayed on the viewer's TV screen and the viewer's command inputs being entered from the control unit.
