In the 1960s and 1970s Dennis Ritchie and Ken Thompson invented Unix, arguably the world’s most important computer operating system. The legacy cannot be overstated, as Unix, its descendants and look-alikes, and its architecture can be found on most computers in existence today.

Is Unix the first operating system?
In 1972-1973 the system was rewritten in the programming language C, an unusual step that was visionary: due to this decision, Unix was the first widely-used operating system that could switch from and outlive its original hardware.
Is Unix dead?
That’s right. Unix is dead. We all collectively killed it the moment we started hyperscaling and blitzscaling and more importantly moved to the cloud. You see back in the 90s we still had to vertically scale our servers.
Is Unix used today?
Proprietary Unix operating systems (and Unix-like variants) run on a wide variety of digital architectures, and are commonly used on web servers, mainframes, and supercomputers. In recent years, smartphones, tablets, and personal computers running versions or variants of Unix have become increasingly popular.
Is Unix 2020 still used?
It’s still widely used in enterprise data centers. It’s still running huge, complex, key applications for companies that absolutely, positively need those apps to run. And despite the ongoing rumors of its imminent death, its use is still growing, according to new research from Gabriel Consulting Group Inc.
How did Unix get its name?
Ritchie says that Brian Kernighan suggested the name Unix, a pun on the Multics name, later in 1970. By 1971 the team ported Unix to a new PDP-11 computer, a substantial upgrade from the PDP-7, and several departments at Bell Labs, including the Patent department, started using the system for daily work.
Which is the oldest operating system?
The first operating system used for real work was GM-NAA I/O, produced in 1956 by General Motors’ Research division for its IBM 704. Most other early operating systems for IBM mainframes were also produced by customers.
