Information Technology Industry TimeLine
-1944 1945-1963 1964-1974 1975-1994 1995-
The present TimeLine page differs from similar pages available on the Internet because it is focused more on the industry than on "inventions". It was originally designed to show the place of the European and more specifically the French computer industry facing its world-wide competition. Most of published time-line charts either consider that everything had an American origin or they show their country patriotism (French, Italian, Russian or British) or their company patriotism.
It includes three kinds of entries :
the major industry companies creations and dismays with their main managers taking office,
the introduction of significant computers or technology by those companies,
some inventions that have taken place in the computer science.
By no means, the list should be considered exhaustive and it is
planned to add to it in the future. Readers are invited to request for corrections or
additions to the author.
While a few dates are recorded with precision, other may be as imprecise as one year. For
instance, companies mergers may require many months to be concluded. Inventions may be
credited of the patent filing or approval. Operation of a system may be dated as day
of shipment or of its actual commissioning by the customer. Products may be introduced not
simultaneously in several countries. In addition, sources may contradict each other. The
wording generally used in this time-line is "introduction" for announcement by
the manufacturer. Actual "delivery" could be significantly later; sometimes, it
never occurred. "Shipment" means delivery of hardware, but actual
"operation" may be significantly delayed.
While over 2400 milestones are recorded here, there is still a lack of coverage of
important fields (peripherals, electronic consumer goods, software companies), several
countries are not yet given the rank they deserve.
This page and its companions focus essentially on the computer industry and its relations with other information processing technology in general. It has been extended of some aspects of the electronics industry that was the cradle of many companies. and inventions of the information technology.
Pre-1945 period is actually the pre-historic era of that industry. Several
inventions had taken place in Europe and USA. However, it has to be remarked that, almost
exclusively in the USA, a calculator industry and a punched card industry was born in the
first part of the century. One possible reason for this incentive for mechanization of
clerical tasks in the USA might be related to the scarcity of workers, even in a country
of immigration. It also underscores the general consensus for increase of productivity in
the U.S. even in the depression periods.
The development of telephone and telegraph operators occurred on a worldwide basis, but
the influence of American investors was generally dominant, although in all countries,
governments decide to administrate or strictly regulate the telecommunications operations.
