Origin of Hello, World!

While several small test programs have existed since the development of programmable computers, the tradition of using the phrase "Hello, world" as a test message was influenced by an example program in the 1978 book The C Programming Language, with likely earlier use in BCPL. The example program from the book prints "hello, world", and was inherited from a 1974 Bell Laboratories internal memorandum by Brian Kernighan, Programming in C: A Tutorial.
