I discovered this advertising of TV sony PRISM G.T. game & television, but I found no information.
Someone has information on this TV?
I am very curious.
Well, judging from what's on the screen in the picture where the kid is standing by the TV... I'd say it might have possibly been a joint attempt by Mattel Electronics and Sony to get the IntelliVision into Japan. If you look closely enough, you'll see Space Armada playing. Anyone that grew up 'tween 1978-1983 (I was 2 in '83 and already playing and hooking up game consoles) that played Mattel's console could probably recognize the game just from the Invaders-like image and iconic border.
@CPC6128 Well, keep in mind Atari for a short time had consoles in Japan. Was just making a somewhat educated guess from the TV showing a screen of Space Armada for INTV.
