This is a great read. For a summary, see Malcom Gladwell’s review at Gladwell.com. Johnson argument that the potential revenue of DVD sales creates a market for television shows and movies that consumers can enjoy viewing several times is intrigiuing, and is a great example of how technology and art influence eachother. The discussion of video games is also worthwhile, as are his references to fascinating psychology studies. (Malcom Gladwell’s books are also great for this reason.)
