Rich-Text History

“Hello World” is the first program one usually writes when learning a new programming language. The first Hello World program appeared in chapter 1.1 of the first Kernighan & Ritchie's original book about C, "The C Programming Language", in 1978 and read like this:

    main() {
      printf(“hello, world\n”);

Since then, Hello World has been implemented in just about every programming language on the planet.
