THE NUMERATOR

Who funds Linux development?

It is often assumed mostly volunteers develop Linux. But major information technology firms invest funds and employee time into the developing the Linux operating system kernel. The biggest single group, "None," consists of developers working on their own time. But the lion's share — 86.1 percent of contributions — was from organizations. (At least one company will not be contributing any longer: SGI claimed bankruptcy earlier this month.)
