For more than half of the fifty years computer programmers have beenwriting code, O’Reilly has provided developers with comprehensive,in-depth technical information. We’ve kept pace with rapidly changingtechnologies as new languages have emerged, developed, andmatured. Whether you want to learn something new or needanswers to tough technical questions, you’ll find what you need in O’Reilly books and on the O’Reilly Network.

This timeline includes fifty of the more than 2500 documented programming languages. It is based on an original diagram createdby Éric Lévénez (www.levenez.com), augmented with suggestionsfrom O’Reilly authors, friends, and conference attendees.
