YAY!!!
IGN*orance* lists FTW.
It is OBVIUS that NES, the one famous Atari the Wii and the first XBOX should be in the top 5.
Because:
Atari - made the console market relevant (alongside with commodore too)
NES - It saved the console market from saturation and crash and revolutionized it.
XBOX - Xbox Live for the first time. Halo Combat Evolved. Enough said.
Wii - It saved the market and revolutionized it again and make a new model to follow by others in the market.
Whoever disagrees with this needs to born again.
