A television viewing control device for recording the viewing time of one or more viewers watching a controlled television set and turning the television set off when a predetermined viewing time limit of any one of the viewers is exceeded. The viewing control device includes a random access memory circuit for semi-permanently storing an assigned individual password for each of a given number of viewers and a predetermined viewing time associated with each of the passwords, a micro processor unit having the capacity for temporarily storing the individual password of each of the viewers watching the controlled set at any particular instance of time, and including polling means operated by a read only memory unit at predetermined intervals of time to compare the passwords in the random access memory and the micro processor unit and to subtract a period of time equal to the predetermined interval from the viewing time associated with each of the passwords in the micro processor unit, and a control switch actuated by the micro processor unit for turning the controlled television set on when a first password is fed into the memory of the micro processor unit and to turn the set off when the time limit of any of the viewers watching the controlled set reaches zero.
