Why is it called hello world?

Question

Why is the indroductory program to every language to print "Hello world!". Is there a historical to reason why that exact phrase is used, or is it just something we've collectively settled on?

Answer 1

Brian Kernighan (creator of C) wrote the first hello world as far as I know. It's a nice tradition, it makes it look like the computer came to life and is announcing it's presence!

Answer 2

because "Hello Mars" is non-sense

Answer 3

Every programming language is a new virtual world.
So while starting work with it "Hello world" is written to welcome that new world in our life

Answer 4

Denis Riches and Brain Kernighan wrote their first program in hello world , computer was than brought to life ,and than Greet the world . I think it is a very cool tradition in programming , mostly
for beginner programmer,and
every language is a new visual world , new syntax and method to work with , its indeed a really cool tradition .
