Which company did IBM acquire for about $34 billion in 2019?

IBM acquired Red Hat for about $34 billion in 2019.

Red Hat was founded in 1993 and became the best-known commercial company built around Linux and open-source software. Its Red Hat Enterprise Linux distribution was widely used by businesses, governments, and other organizations that wanted enterprise support for open technologies.

IBM announced the acquisition in October 2018 and completed it in July 2019. Red Hat continued to operate as a distinct unit, and IBM presented the purchase as central to its hybrid-cloud strategy. The price is usually described as approximately $34 billion because the transaction was an all-cash deal valued at $190 per share. This was not IBM's purchase of Linux itself: Linux is an open-source operating system and was never owned by Red Hat.
