I have to disagree as well that it is the 360 that changed the industry. The online features that we have in consoles today have been in plans much earlier than most of us tend to believe.
Both Sony and MS have been waiting for the right time to add these features in a manner that it gives the maximum value to the consumers.
Sony has been talking about distribution, online gaming, movie and music management in PS2 since before its release. It was part of the "Computer Entertainment System" vision. It was only a matter of appropriate execution. And the PS2 did not seem like the best option to try and do all these meaningfully. Their plans found fruition in PS3
The XBOX did try to implement those ideas but it wasnt that well implemented either.
Sega showed that a good idea is the worst if not done at the right time. The same visions they expressed with their online plans for the Saturn and the DC are strikingly similar to what Sony and MS did this generation. But the technology at the time and costs meant a very impractical execution both business wise and consumer wise.
The console industry today is formed by a simultaneous/joint effort by both Sony and MS. Someone happened to release its product earlier. And despite who is or was having the best service and implementation, the industry would have changed to what we have today regardless because users for the first time could enjoy these features and services better and easy at lower costs n a PS3 and 360.
But Nintendo ALSO contributed in its own way. Because for the first time people care about motion control features and the industry is evolving towards incorporating hybrid motion sensing and traditional game controlling methods.
Planning a vision and successfuly executing a vision aren't the same thing. Sega deserves credit for bringing innovation to its hardware but MS deserves credit for actually helping innovate the market.
Its not like the Iphone, when first introduced, did anything not offered by other smartphones. However, its success have pushed others to put greater effort to take advantage of the accelerated growth of the smartphone market. A phone like the Iphone was destined to happen but Apple was smart enough to use the success of its Ipod and a very user friendly and sleek interface to realize that phone and move the whole market forward as a whole in a matter of 2 years. For US, the smartphone market is going from a very niche part of the cell phone market to literally the cell phone market in a relatively short period of time.
Sony, MS and Nintendo have all used their current gen hardware to push content delivery on console to a different level. MS's Live on the 360 has been spearheading that effort and now we have three centralized online content delivery services that are much further along than they were 4 years ago. We are going from 2 million subscribers of Live in late 2005 on the Xbox1 to 60+ million making use of their console online services in some form or fashion in late 2009.
