An apparatus and a method for automatically displaying broadcasting program information in a television receiver which has a microcomputer for controlling the entire system operation, first and second tuners for tuning in to television broadcasting signals corresponding to selected channels under the control of the microprocessor, respectively, first and second tuner decoders for decoding the television broadcasting signals tuned by the first and second tuners, respectively, and a signal processor for processing output signals from the first and second tuner decoders to display them on main and sub cathode ray tubes, respectively. The apparatus comprises a first switch for selecting a video signal from the second tuner decoder or an external video signal in response to a first switching control signal from the microprocessor, a broadcasting program information output unit for detecting, storing and outputting broadcasting program information from the first tuner decoder in response to a program information storage/output control signal from the microprocessor, and a second switch for selecting the broadcasting program information from the broadcasting program information output unit or the video signal selected by the first switch in response to a second switching control signal from the microprocessor.
