In the summer of 1969 computer scientists Ken Thompson and Dennis Ritchie created the first implementation of Unix with the goal of designing an elegant and economical operating system for a little-used PDP-7 minicomputer at Bell Labs. That modest project, however, would have a far-reaching legacy. Unix made large-scale networking of diverse computing systems — and the Internet — practical. The Unix team went on to develop the C language, which brought an unprecedented combination of efficiency and expressiveness to programming. Both made computing more "portable". Today, Linux, the most popular descendent of Unix, powers the vast majority of servers, and elements of Unix and Linux are found in most mobile devices. Meanwhile C++ remains one of the most widely used programming languages today. Unix may be a half-century old but its influence is only growing.
