Hello World Program Origins

Many software developers have seen examples of the "Hello World" program in textbooks and may have even written one. The purpose of the program is to provide the fewest statements and produce some output, notably the message "Hello World."

Most programming textbooks have examples of the "Hello World" program, few people know its origins. The first instance of a documented "Hello World" program appeared in A Tutorial Introduction to the Language B that was written by Brian Kernighan, in 1973.

B was a language developed at Bell Laboratories that was a precursor to the popular programming language, C. While this programming language has long been forgotten, its impact is still felt in textbooks and by software developers.
