Disintermediation

The disintermediation process
Intermediary B may be bypassed by A to connect with C directly.
Although Webvan failed in its goal of disintermediating the North American supermarket industry, several supermarket chains (like Safeway Inc.) have launched their own delivery services to target the niche market to which Webvan catered.

Disintermediation is the removal of intermediaries in economics from a supply chain, or "cutting out the middlemen" in connection with a transaction or a series of transactions. Instead of going through traditional distribution channels, which had some type of intermediary (such as a distributor, wholesaler, broker, or agent), companies deal with customers directly and vice versa, for example via the Internet.
