DARPA is a high-level United States of America ARMY project that involves the creation of a low-speed data network. It is an acronym that stands for:
Denied All Reasonable and Practical Access
After funding fell through from the US government, it was financed by the pr0n industry and thusly thrived.
DARPA has been involved in a number of important scientific discoveries such as the invention of bobble-heads and the subliminal messaging used in all modern mmorpgs such as WoW (thus benifitting its sponsors in the pr0n industry)
