From there it spread to virtually every programming language textbook, manual, and tutorial.\n\n---\n\n### How it happened\n\n| Year | Publication / Event | What it did |\n|------|---------------------|-------------|\n| **1972** | *A Tutorial Introduction to the Language B* (Kernighan) | First known “Hello, World” example, printed as a complete, runnable program that simply prints the string *Hello, World!* on the screen. |\n| **1978** | *The C Programming Language* (Kernighan & Ritchie, 2nd ed.) | The same example appears as the very first program in the book’s Chapter 1, now written in C: <br>`int main(void) { printf(\"Hello, world!\\n\"); return 0; }` |\n| **Early‑80s** | Textbooks for Pascal, Algol, Lisp, etc. | Authors copied the style as a gentle “first step” for newcomers, because the program is tiny, portable, and demonstrates the basic syntax of *any* language (a function, a string literal, output). |\n| **1990s–present** | Online tutorials, IDE “new‑project” wizards, “Hello, World!” contests | The phrase has become a cultural meme—sometimes used humorously, sometimes as a benchmark for compiler/IDE setups. |\n\n---\n\n### Why “Hello, World?”  \n\n1. **Simplicity** – It needs only a single statement that produces visible output.  \n2. **Universality** – Every language can display text, so the example works everywhere.  \n3. **Human touch** – Greeting the world feels friendly, making the first encounter with a language less intimidating.  \n4. **Historical inertia** – Once the K&R book popularized it, instructors and textbook authors kept re‑using it, cementing the tradition.\n\n---\n\n### Earlier precedents (pre‑1972)\n\n* **1967** – The *BASIC* language manual (by Dartmouth) includes a program that prints “Hello”.  \n* **1965** – The *IBM System/360* assembly language manual shows a sample that prints “HELLO”.  \n* **1960s** – Various teaching systems (e.g., the *MIT* “Intro to Computer Science” labs) used short “greeting” programs, but none used the exact phrase *Hello, World*.\n\nThese earlier examples show that the idea of a minimal “print a greeting” program existed, but the exact wording **“Hello, World!”** (capitalized, with a comma) is traceable to Kernighan’s B tutorial and then to K&R’s C book.\n\n---\n\n### TL;DR\n\n*The phrase “Hello, World” as a programming example was coined by Brian Kernighan in his 1972 B tutorial and cemented by the 1978 K&R C book. Its brevity, universality, and friendly tone turned it into the canonical first program for generations of programmers.*","function_call":null,"reasoning":"The user asks: \"What is the origin of the phrase Hello, World?\" They likely want a concise answer about the phrase used in programming tutorials, its origin in Brian Kernighan's 1978 book \"The C Programming Language\", earlier in \"A Tutorial Introduction to the Language B\" (1975) and earlier in the 1972 \"The C Programming Language\" (actually the first appearance was in Kernighan and Ritchie, 1978).
