The Xbox 360 is the successor to Microsoft's Xbox video game console, developed in cooperation with IBM, ATI, Samsung and SiS.
At launch, the Xbox 360 was priced at US$399 and the Core System was priced at US$299.
Businessweek magazine compiled a report that estimates the total cost of components in the Xbox 360 premium bundle at US$525 at launch,[16] sans manufacturing costs, meaning that Microsoft initially lost money on every Xbox 360 system sold.
The Xbox CPU also contains ROM storing Microsoft private encrypted keys, used to decrypt game data.
