I would also recommend Tim Wu's book "The Master Switch" that discusses media monopolies in the U.S. in historical perspective, from the telegraph and early telephone on to movie studios and on to the Internet nowadays. As the book explains, the Internet itself in its current open form is a historical aberration, similar to the multitude of choice in the early days of radio which was short-lived, to be soon replaced by monopolies under the government's helping hand. In fact, many technological inventions would not even have been possible when they happened (and some were delayed by decades) because of large monopolies. The origination of the Internet itself, the book explains, is a direct result of the splitting of AT&T in 1984, which allowed, for example the standard modem jack to exist (jacks and equipment were proprietary before that), and which disallowed AT&T from getting in the Internet business as an ISP. It seems that these lessons have begun to be, once again, forgotten by our modern generation. The solution to all this would be that the government properly fulfills its role of ensuring free market access and prevention of monopolies. It would also entail what's termed a "separations principle", the creation of distance between each of the major layers in the information economy.
