Today in the cortex, a flyer for Space Invaders, which helped solidify video games as popular entertainment. Invaders' biggest contribution to the North American video game industry was probably how it brought coin-op games out of bars and bowling alleys, and into restaurants, coffee shops, hotel lobbies and other mainstream venues. Such did video arcade games move from a smokey niche market and into popular consciousness.
But that's nothing compared to how Space Invaders affected Japan when original manufacturer Taito released it there. The game was so popular, with so much change being dropped into the machine to play, that the Bank of Japan had to triple 100-yen coin production to keep it in circulation.
This flyer sent by North American licensee Midway to distributers is mighty explosive. A fitting graphic for a game that set the world on fire. For more information on Space Invaders, consult your local Dot Eaters entry.
