Numbers: check http://www.softwaretop100.org/top-25-gaming-companies-2010 for the rankings of the top 25 by revenue. We see Nintendo, Activision Blizzard, Sony, and the rest of the top 10 make up over half of the estimated global game revenue. 10 companies out of hundreds? thousands? who knows? The iOS market will probably move more and more towards this as the big publishers like EA continue to press their marketing advantage to sell their games, but the nice thing is there is always an opportunity for the little guy with the killer game to sell just as many copies as EA.

Compared to the console and PC gaming world I would imagine the disparity there to be even greater than this. EA, Take Two Interactive, Nintendo, Capcom, Microsoft, Activision Blizzard, Sega, Sony, etc are likely the top 0.01% when it comes to developers and probably take in almost all the (it's too damned early for me to actually do the research, sorry). The important difference here is that in iOS, as of now, the top 1% is only taking in 30% and that those developers are made up of a far greater number of indie studios.

...think of the faculty at a place like the University of Phoenix

To anyone who is any anyway involved in education or has even received one (I mean an education, not just a piece of paper) the thought of all universities being run by U of Phoenix types leaves me even more frightened for the future than normal. Watch PBS's Frontline or just work with someone with a University of Phoenix degree and you'll see what I mean. I have a much better idea: how about we make all universities the opposite of the University of Phoenix. How about all schools have actually competent people get paid to actually teach people who actually give a shit about learning something instead of just adding a few extra letters to their resumes (or in the case of the U of Phoenix teachers, just getting stock options in the University and an extra paycheck)?
