The Internet is the latest in a long succession of communication technologies. The goal of thiswork is to draw lessons from the evolution of all these services. Little attention is paid to technologyas such, since that has changed radically many times. Instead, the stress is on the steady growth involume of communication, the evolution in the type of traffic sent, the qualitative change this growthproduces in how people treat communication, and the evolution of pricing. The focus is on the user, andin particular on how quality and price differentiation have been used by service providers to influenceconsumer behavior, and how consumers have reacted.There are repeating patterns in the histories of communication technologies, including ordinarymail, the telegraph, the telephone, and the Internet. In particular, the typical story for each service isthat quality rises, prices decrease, and usage increases to produce increased total revenues. At the sametime, prices become simpler.The historical analogies of this paper suggest that the Internet will evolve in a similar way, towardssimplicity. The schemes that aim to provide differentiated service levels and sophisticated pricingschemes are unlikely to be widely adopted.Price and quality differentiation are valuable tools that can provide higher revenues and increaseutilization efficiency of a network, and thus in general increase social welfare. Such measures, mostnoticeable in airline pricing, are spreading to many services and products, especially high-tech ones.However, it appears that as communication services become less expensive and are used more fre-quently,those arguments lose out to customers? desire for simplicity.
