Well, there is the question folks. besides the wii , which i think has been a huge money maker for Nintendo, i would like to know, despite market shares, of all of the generations, how much profit Companies actually brought to the table...  i started wondering about this,when i read something about microsoft losing money in their first box, while gamecube made profit... when i tought gamecube came in third last gen?? so im wondering how far behind was the cube to the ps2?? (revenue wise) ( we all know about market share).  I would also like to read ur opinions about the matter in every gen that Nintedo has been in.

Wii then probably NES since it sold for the longest.

probably NES

if Handhelds are included GB and GBC

the Nes? even when it took nintendo around 3 years trying to make it in to the american market?? they most have invested some money there dont you think?

I would guess one of the old systems like NES and SNES. The budget of those games had to be incredibly low.

Edit: Actually it must have been the Gameboy and Gameboy Color. Those Pokemon games must have made billions. And ofcourse low budget games.

probably Wii, DS & N64

Probably the Wii.

Your questions aren't all the clear, though I'd dare to say that the Gameboy was their biggest money maker. It's one of the best selling platforms of all time, and it had some ridiculous first party sales (Pokemon comes to mind).

I can't break it down by console, but here are the financials.

I would say GameBoy was Nintendo's highest profiting system. However that depends if GameBoy:Colour is not included maybe not. I think Nintendo DS is and has been Nintendo's most profitable system to date. But if your not counting the Wii or DS, then I'd have to say GameBoy:Advance (If you don't count colour in the origional GameBoy list).

Why do I think GBA was the most profitable. A) Nintendo had to sink barely anything into R&D the technology didn't have to be invented it didn't have to be tested. Nintendo made the GBA for a profit from day one. I think the origional GameBoy required alot of R&D and origionally how much profit did Nintendo make from every hardware unit sold? probubly not much considering the technology was brand new and never done before.

So the GBA would need little to know R&D and games were cheap to develope for it. Pokemon and other franchises pushed millions of GBA's. Some have argued that the GBA kept Nintendo profitable during the GameCube era. Even though I know Nintendo made a profit on every GC sold. However that doesn't change the fact that GBA's must have turned a huge profit!
