"International Business Machines, the century old computing
company, with a focus on enterprise computing, is a company with
many open source projects: Eclipse, the framework, the development
of the Linux kernel, which IBM helps with hired programmers to
contribute to the Linux kernel, SELinux, Xen, among many other
projects, which could not fit here.
"IBM first got involved with Linux in 1998, and with Linux, it
saw an opportunity to add value to the services it already offered.
Since Linux is excellent in scalability, from medium to large
scale, IBM began using Linux in its activities.
"In 1999, it created the Linux Technology Center, to integrate
Linux to the services it was offering, but also to improve the
Linux kernel for its products. One result was the release of the
Linux kernel for various platforms: x86, mainframe, PowerPC, and
more recently the Cell processors (Playstation 3)."
