A karaoke network system is composed of a central station 1 for serving data, and a local terminal 3 connected to the central station through a communication line 2 for presenting an event according to the served data and being switchable between a forking state and an idling state in response to a request The central station responds to a call from the local terminal for serving a song data representative of a karaoke event to the local terminal through the communication line. The central station further down-loads a program data which sequentially prescribes spare events into the local terminal through the communication line. The local terminal operates in the working state where a request is present for presenting the karaoke event based on the served song data, and otherwise operates in the idling state where a request is absent, for sequentially presenting the spare events according to the down-loaded program data, so as to fill a blank period of the idling state. The spare events may comprises advertisements, new songs or demonstrations of available songs. <IMAGE>
