Hit economy: in the former economy, hits were used to cross-subsidize the many less successful titles - which in turn were used to incubate possible hits. (Ratio 80/20).
Long-Tail-Economy/Anderson: there is a prehistory that had nothing to do with the internet: Order numbers, parcel delivery, credit cards, databases, even barcodes. These things have evolved over decades. The Internet has connected them to a network in no time at all.
