ok back to topic seriously...
It really doen't matter who's first. We can argue for as long as our lifetime to decide.
Each platform deserves credit, not only the PS2 for they offered games for the "casual" audience (from atary to last gen consoles). Some did more effort, some didn't. Even PC and internet influenced in the casual gaming boom. So there really is no absolute "pioneer".
However, the only company that on this gen considered the non gamers and former gamers a priority in order to expand the market was Nintendo with the Wii. No other console approached the non-gamer with so much effort and passion that Wii, other consoles started as a hardcore platform and then moved to the "casual" eventually.
