Chris is President of Ur Studios, Inc. He has been active on the Internet since 1972, when he was introduced to Arpanet as a student at Harvard. As a graduate student at Caltech, he introduced the use of interactive remote computing by using the Macsyma program at MIT over the Arpanet. Later he co-wrote with Stephen Wolfram the first commercially available symbolic math package, SMP, which was a precursor to Mathematica. He is currently the editor of the archive for the Usenet newsgroup rec.puzzles. Cole co-founded his first software company in 1978, and has been a founder of several companies since then. In the late 1980s, Cole became interested in the Internet as a medium for virtual communities, and several of his recent companies have explored this area, including Worlds, Inc. and Ur Studios, Inc.
