Here's the top amount of consoles/handhelds sold between each company (Wikipedia numbers)
Nintendo
| Consoles | LTD Numbers |
| Game Boy/GBColor | 118.69 million |
| DS | 100 million |
| GB Advanced | 81.44 million |
| NES | 61.91 million |
| Wii | 50 million |
| SNES | 49.1 million |
| Nintendo 64 | 32.93 million |
| GameCube | 21.74 million |
| Virtual Boy | 770,000 |
| Total: | 516.58 million |
Nintendo has currently shipped more then 516 million console and handhelds world wide.
Sony
| Consoles | LTD Numbers |
| Playstation 2 | 136 million |
| Playstation | 102.49 million |
| PSP | 50 million |
| PS3 | 21.3 million |
| PocketStation | 4.5 million |
| Total: | 314.29 million |
Sony has currently shipped more then 314 million consoles and handhelds world wide.
Sega
| Consoles | LTD Numbers |
| Mega Drive/Genesis | 29 million |
| Saturn | 17 million or 9.5 million |
| Master System | 13 million |
| Game Gear | 11 million |
| Dreamcast | 10.6 million |
| Mega-CD | 6 million |
| Nomad | 1 million |
| Total: | 80.1 - 87.6 million |
Sega has shipped in between 80.1 - 87.6 million consoles and handhelds. The reason for the two different numbers for the Saturn is because there was two different sources saying two different amounts, VG Chartz has the Saturn at 8.82 million so I'd say the 9.5 million is the better number then 17 million.
Microsoft
| Consoles | LTD Numbers |
| Xbox 360 | 28 million |
| Xbox | 24 million |
| Total: | 52 million |
Microsoft has currently shipped over 52 million consoles world wide.
Atari
| Consoles | LTD Numbers |
| 2600 | 30 million |
| Total: | 30 million |
Now obviously there are other consoles like the 5200 and the 7800 but I could not find any toal numbers for them, so for now the Atari is incomplete.
I'm going to stop here, there are other companies but the number's are very different for alot of websites so it wouldn't be very accurate. Anyway there you have it, it took Nintendo 25 years to sell a whopping half a billion consoles and handhelds, how high can that number go, possibly a billion? Coming up the rear with an impressive 314 million consoles and handhelds sold in just 15 years is Sony, once again it'll be interesting to see how high this number will go. Next comes Sega selling roughly 80 - 87 million, hopefully some day we'll see Sega jump into the console wars once again. After Sega is the new comer Microsoft selling a very respectable 52 million consoles, no handhelds yet.
I can't say much about Atari it's to bad I couldn't find the numbers for the 5200 and 7800. I know that the 5200 bombed bad and the 7800 didn't do to well at all. By the time the 7800 was cancelled the NES owned 80% of the North America market and Atari only had 12%, so the other consoles couldn't have sold well.
