The C programming language came out of Bell Labs in the early 1970s.
According to the Bell Labs paper the development of the C language by Dennis Ritchie, “The C programming language was devised in the early1970s as a System Implementation Language for the nascent Unix OS. Derived from the typeless language BCPL, it evolved a type structure; Created on a tiny machine as a tool to improve a meager programming environment.”
Originally ken Thompson, a Bell Labs employee, desired to make a programming language for the new Unix platform.
Thompson modified the BCPL System Language and Created B.
However, not many utilities were ever written in B due to its slow nature and inability to take advantage of PDP-11 features in the OS. This led to Ritchie improving on B, and thus creating C Language.
