 <p>The Medley system was created at Xerox's Palo Alto Research Center (PARC). PARC was the cradle of the modern graphical user interface and its design thinking continued with the development of Medley Interlisp, an extensible graphical operating system with nearly limitless possibilities for customization. Whatever the task, using Medley you can design a custom workflow to help accomplish it.</p>
 
-<p>Interlisp had its beginnings as a DARPA sponsored Lisp environment for reasearchers. Interlisp was then ported and expanded into Interlisp-D, first released by Xerox and distributed commercially until its development tapered off in the 1990s. Now this classic software system is running again on your favorite operating system. The project is more than a trip down memory lane: our mission is to expand the scope of what Medley can do, fulfilling its promise of software tools limited only by the user's imagination. Dive in and explore the language, the tools, and the myriad applications, experiments, and playful creations that were crafted in and for Interlisp.</p>
