I saw this on someone's wall a while ago but just now ran across it on the web. This is a chart of all major programming languages, how they are related, and what years they were around. It's an interesting view of where we have come from. Two of the first 4 languages (Fortran, Lisp, B-O, and IAL) are still in use today in one fashion or another. I find it intriguing to look at the ancestors of many of our modern languages.
