I don't think 'corporation' is a required title for the concept to apply. Large command-oriented economic drivers have existed for a long time. The Roman army was one, it's economic function the looting of conquered territory. Notice that when it could no longer accomplish that function, things began to turn south for Rome.
We are observing the decentralization of economic authority, common throughout history, but usually a side-effect of economic decline and/or societal collapse; maybe more correctly a side-effect of the movement from specialized occupations back to subsistence farming.
This decentralization seems to be different, and appears to be driven by the unprecedented communication, access to information, and wide audience granted by the Internet.
