"Red Hat, Novell, and IBM all have substantial software
businesses, with heavy investments in Linux, so it makes sense that
they'd contribute heavily to the Linux kernel. But according to new
data Jonathan Corbet of LWN.net announced at the Ottawa Linux
Symposium on Wednesday, Intel has surged from 2.3 percent in 2007
to 4.1 percent in 2008 to 6.9 percent in 2009.
"Red Hat still sits atop the corporate pile of contributors with
12.3 percent, but within the next two years it's possible that
we'll see Intel top it. Since Corbet last compiled his kernel data
in 2008, 2,559 developers added 4.8 million lines of code. Among
the 339 employers found in Corbet's data, Intel ranks second."
