RedHat is the most known and biggest company in the world whose business is entirely based on Linux. It's the first distribution maker that has quoted its shares at Nasdaq and one of the not so many companies that has built a successful Linux business model.
Originally founded by Marc Ewing, it was purchased in 1995 by Bob Young's ACC Bookstores. During the following years, version after version, it has gained a reputation of distro good for servers (even if by far not the best one, according to purists) with easy installation and configuration tools.
The first public release of Red Hat Linux (version 1.0) is dated 1994, after the older historic distro as Slackware, but still largely before the big Linux boost of the following years.
