Samsung and Apple have been at war in the device market for years now--especially the smartphone business. (The war includes legal battles on patent infringement too, not just market share.) But all the while, they've also been doing business together. Samsung is a huge computer chip manufacturer--and Apple, because of its dominance, needs more chips than just about anybody. So Samsung has long been manufacturing a large portion of Apple's chips--the tech that powers your iPad and iPhone. Apple custom-designed the chips, but rival Samsung made them.
Now the Wall Street Journal reports that Apple isn't giving Samsung its chip business anymore. And that spells a $1 billion loss in Samsung's chip business--from a $200 million operating profit last year to an $800 million loss this year. Steve Jobs may be gone, but Apple still plays hardball.
