Interesting Hello, World! tidbit

While I was reading Practical Common Lisp, I found the following footnote.

The venerable "hello, world" predates even the classic Kernighan and Ritchie C book that played a big role in its popularization. The original "hello, world" seems to have come from Brian Kernighan's "A Tutorial Introduction to the Language B" that was part of the Bell Laboratories Computing Science Technical Report #8: The Programming Language B published in January 1973. (It's available online at http://cm.bell-labs.com/cm/cs/who/dmr/bintro.html.)

Also interesting and related is the ACM "Hello World" project, where one will find how to print "Hello, World" in nearly 200 languages.
