| Abstract: | The causes of market concentration in advertising-supported markets such as sports, news and email are examined in this artice. Particularly, the relationships between concentration and product differentiation, economies of scale, market size, advertising, content costs and multi-market ownership in online markets are explored. As was expected, differentiated markets with low content costs and little multi-market ownership are less concentrated. |
