Home > Category killer

An example of a category killer business is eBay. eBay as an online auction site has a natural monopoly, as buyers and sellers will naturally gravitate to the largest, most liquid, market. As a result, their business has almost no competition and has forced similar auction sites like the ones run by Yahoo! into a very small portion of the market. eBay now commands over 90% of the consumer-to-consumer auction market.
