When was "Hello, world!" first used to introduce a new piece of technology?

And why aren’t engineers sick of it and making funny plays on it?

Well, it is usually used to confirm that a development environment is working. If i need to check if a LAMP stack is working I usually start with:

echo “Hello World”;
echo 4 *16;

According to Wikipedia
“While small test programs 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 seminal book The C Programming Language. The example program from that book prints “hello, world” (without capital letters or exclamation mark), and was inherited from a 1974 Bell Laboratories internal memorandum by Brian Kernighan, Programming in C: A Tutorial, which contains the first known version”

I remember clearly. Oomla grunted it when he perfected the first wheel.

Don’t you ever want it to say something like O hell, world! Or even wilder things?

Did Oomla play ventriloquist and pretend the wheel said it?

And Apple used something similar in 1984

“Hello world” is about as old as the first program Look up old archives of computer magazines that have an introduction to programming, or even manuals to old computers that had a built in BASIC and you’ll find it. Probably way back in the 70s, at least.

I have no idea how old it is, I imagine very old. I imagine the reason it is so popular is because of how useful it is. Little hello world scripts are probably the first step and best way to jump in to a new computer language. It is an ideal way to show how a certain condition can lead to a certain function, and in programming, there are lots of conditions leading to lots of different functions.

K&R, first published in 1978. I’ve got a first edition somewhere; it was standard issue at Bell Labs.
