In 1986, slide and transparency overhead projectors were standard business meeting equipment. A group of engineers at InFocus in Portland’s Silicon Forest knew there had to be a better way. They invented the first digital projector and eliminated the absurd cost and colossal hassle of having to have slides reprinted every single time a company made a change to its pitch deck or sales presentation.  Their later innovations included the first DLP projector, the first projector under 5 pounds, the first interactive whiteboard, and the first ultra-thin projection television.  www.infocus.com
