Jeff Jarvis explains in his book What Would Google Do?, how new economic principles have evolved and how he has grown into/adapted to this new system. He uses therefore illustrative examples from the new media industry (e.g. blogs such as his own buzzmachine.com and many more) but he also compares to the old world, where control of content and scarcity have been the rule. And he gives many examples of how young, innovative companies have emerged from the classical media market or have taken the chance to gain some momentum in the internet because the classical publishers have been too slow.
This article here should be an extended version, since it is used as a discussion base for the course "Digital Media" at the University of St. Gallen, which will take place next week. So as Jarvis puts it in his book: "Free is a business model" I will provide here a summary of the first, more important part for discussion, so that all of my colleagues can profit from my knowledge.
So as mentioned here, the book is divided into 2 respectively 3 parts: The first part covers the introduction and the "Google Rules" (no not the 10 Things Google has found to be true). This summary will focus on this part. Second part is called "If Google Ruled The World", where it is about different industries and how the principles from the first part would apply there. The final part is called "Generation G".
