Disclosed is an apparatus for controlling synchronous display of data to be transmitted among a plurality of terminals interconnected over a communication line. The apparatus comprises a data segment device for, in a transmitting operation, segmenting the data into some parts at predetermined intervals; a communication device for, in a transmitting operation, transmitting the data to the receiving terminal and then receiving a reply therefrom every time a part of the data has been visible on the receiving terminal display, and for, in a receiving operation, receiving the data from the transmitting terminal and then transmitting a reply thereto every time a part of the data has been visible thereon; a display control device for, in a transmitting operation, controlling a display device to visualize the same part as is transmitted to the receiving terminal at first distinguishably from the other parts which are already visualized and then indistinguishably therefrom when the communication device receives a reply from the receiving terminal that the same part has been visible thereon, and for, in a receiving operation, controlling the display device to visualize the part of the data received from the transmitting terminal; and a reply sending device for, in a receiving operation, sending a reply to the transmitting terminal every time a part of the data transmitted from the transmitting terminal has been visible thereon.
