"In Net Profit, author Peter Cohan maintains that the internet, while unique in aspect, is not so different in form from other industries. Using tried-and-true economic analysis, he examines nine specific internet business segments and identifies the underlying dynamics of each. He compares the strategies and practices that distinguish each segment leader from its peers. He cuts through the hyperbole surrounding internet business to make economic sense of the Web and provides readers with a thorough understanding of today's industry. Along the wey Cohan also offers a wealth of savvy investment advice."--Jacket.
