devoted to research projects at the convergence of multimedia and technology, the media lab was widely popularized in the 1990s by business and technology publications such as "wired" and "red herring" for a series of innovative but practical inventions in the fields of wireless networks, field sensing, web browsers, and the world wide web. the media lab works primarily on the theory and real-world implementation of physical-virtual interface. as negroponte envisioned it, interface has become an architectural problem. there have been numerous research spinoffs growing out of the media lab, including one laptop per child (olpc), electronic ink, and lego mindstorms.
