Sony(Ps3, PsP,Ps2) and Microsoft(Xbox360)
greed
Because Nintendo and SEGA are competing companies, it is assumed that Mario and Sonic should fight each other.

Well, you have to think that the console (PS1) and the game you are looking for are both by Competing companies. Nintendo created Mario, so they own all rights to it. I highly doubt they will ever have them on Playstation.
it is an arrangement, where two or more companies help each other to market their products. However, the products have to be complementary and not competing against each other.
They are probably rivals because both are the best search engines/companies. They are 'competing' against each other for fans and fame. I don't think it's anything personal against the creators.
He was competing against David Archuleta. And David Archuleta SO should of won!!!
Probably Insurance companies because they're always competing, other companies that advertise a lot are Car companies, and Cell phone carriers, again, because they're always competing.
interlocking directorates :)
Try your best
Nintendo is one company. therefore, there is one.
People do sometimes get perfect averages. It is important to remember though that you are not competing against them, you are competing against you.
