The article describes how the time-sharing industry constituted a major sector of the computer services industry in the U.S. Time-sharing developed in the mainframe era where a system was consisted of a large central computer to which many terminals were connected. Its market was existed because time-sharing was only means of providing a personal computing experience at a reasonable cost. It is noted that the Compatible Time Sharing System, the first experimental time-sharing system, was demonstrated at the Massachusetts Institute of Technology (MIT).

The article presents developments in the computer software industry in the U.S. It offers information on the two conferences that highlight the technological innovations in the personal computer industries and provide opportunities to its attendees on how to solve technical problems involving computers. It also mentions the issues of "Annals of the History of Computing" edited by Bernard Galler which features the early computing technology and the tales of how engineers and programmers contributed to this field.

The article reports on the writing of international computing history. There is no second thought to the fact that the United States is ruling the computer industry and technological developments. There is a need for an international computing history. A few assumptions have been made like large-scale information processing requires mechanization and it is only big corporations who need large-scale information processing. Three different approaches have been discussed to write international computing history. First approach is to write local histories of computing in other nations apart from the U.S. A few historians have already written history of computing of their specific countries. But these kind of writings are partial toward achievement of one's country. Second approach refers to the comparative studies of two or more countries. This will give a picture of similarities and dissimilarity between the nations. Third approach is based on international relations between countries. There are various advantages of writing an international history of computing, including knowledge about new perspectives and methodologies used in the field of computing.
