They've never really been in the business of "making things" as end-users would see it. They've designed chips and reference PCBs, but they contract outside foundries for manufacturing (unlike, say, Intel, who have their own fabs) and the silicon goes to retail partners like ASUS and Gainward and many others to actually put into the channel (with minor downstream customization like custom heatsink designs). They've only recently actually sold some things directly to customers, like the SHIELD gaming handheld.
