Pong is one of those cases where it isn't the technical "first" of anything objective. It's not the first video game, the first arcade game, the first home video game, the first ping-pong video game, it's not even the first game Nolan Bushnell was involved with. But it was the first arcade game that was a really big commercial success, that attracted leagues of imitators, etc. And the same is true of Home Pong.
