The Internet is characterized by competition between platforms which bring together potential partners of exchange. The degree of competition between these multi-sided platforms und market concentration are determined through (1) the strength of the direct and indirect network effects, (2) the extent of economies of scale, (3) the risk of congestition, (4) platform differentiation, and (5) the possibility of multi-homing. Depending on these factors different market concentrations and barriers to entry result. While there is no general tendency for concentration in the Internet and no general need for special market regulation of online content providers and intermediaries, single platforms may still have long lasting and significant market power which is unlikely to erode fastly, as the example of ebay illustrates.
