In the late 1990s, IBM began considering the Linux operating system. In 2000, IBM announced it would promote Linux. In 2001, IBM invested $ 1 billion to back the Linux movement, embracing it as an operating system for IBM servers and software. Within a decade, Linux could be found in virtually every

Linux has run on IBM POWER systems since 2001, when a team created a new, 64-bit port for the Linux kernel to allow the OS to run on PowerPC processors. The first system to fully support the 64-bit Linux kernel was IBM's POWER5, created in 2004. It was followed by POWER6 in 2007 and the current
