Big Thinkers is a former ZDTV (later TechTV) television program. It featured a half-hour interview with a "big thinker" in science, technology, and other fields. The show was originally hosted by Mark Eddo, later replaced by John C. Dvorak. In 2001 the show changed its format, transforming from a weekly half-hour interview to a documentary-style program. This new format was initially referred to on the TechTV website as Big Thinkers 2.0.
