The term business model became popular only in the late 90s, which, personally I think is related to the rapid erosion of prices in the IT and telecom industry. The roots of my assumption lie in Transaction Cost Economics (TCE). Because it became so cheap to process, store and share information across business units and other companies all the way to the customer, many new ways of doing business became possible: Value chains were broken up and reconfigured; Innovative information-rich or -enriched products and services appeared; New distribution channels emerged; More customers were reached.
