The first program you learn in any computer program language is “Hello World”. The “Hello World” program outputs a text message “Hello World”. So of course my first entry in this blog is the history of Hello World.

Hello World program is used because it is the simplest in any computer program language and it is very easy for anyone to understand. Hello World was first used by Brian Kernighan, 1972 in his “A Tutorial Introduction to the Language B”
Language B was written at “Bell Labs” and was replaced by the language C. Hello World program was also featured in the book C Programming Language (2nd Edition). Language C has been the influence for many of the computer programing languages that are used today.
Since “Hello World” was written by Brian Kernighan web design and development students across the world have been writing computer programs in html, PHP, Java, JavaScript, C#, and many others displaying “Hello World”.
