Bolt Beranek and Newman Inc. ( BBN , also BBN Technologies ) is an American company that was founded in 1948 for the planning of acoustics and contributed significantly to the development of information technology.

history

BBN was founded by Richard Bolt and Leo Beranek , who were professors at the Massachusetts Institute of Technology and after a year their associate Robert Newman involved. The reason for the partnership was Bolt's overload with his assignment to plan the acoustics for the General Assembly of the United Nations . In the 1990s, the company changed its name to the abbreviation BBN, which its subsidiaries already had in the name.

In 1963 the Association for Computing Machinery published a text by Bolt Beranek and Newman. It describes the experimental operation of a remote computer by dialing a telephone and its spoken feedback. Such investigations into acoustics as a means of basic communication resulted in the competence of BBN in the creation of the first computer networks , the feasibility of which had to be proven by means of existing analog telephone networks.

In 1969, BBN realized the Interface Message Processor , which not only enabled the first computer network, but also the later Internet usability with a wide variety of devices. The early analysis of a denial of service from 1980 comes from Bolt Beranek and Newman.

In 1962 BBN became a founding partner of the engineering company Müller-BBN GmbH based in Munich . The five shareholders included Leo Beranek , who represented BBN, the acousticians Lothar Cremer , Manfred Heckl , Ludwig Schreiber and Helmut A. Müller . In 1972 BBN sold its shares to Leo Beranek and former employees of Müller-BBN . The company name was changed to Müller-BBM .

In the mid-1980s, the group included not only the subsidiary BBN Communications in the United States, but also, for example, BBN Communications UK in Great Britain and BBN Computer in Hong Kong . At the same time, for example, BBN repeatedly examined the effects of industrial noise on whales .

BBN Technologies has been a subsidiary of the US defense and technology group Raytheon since 2009 .
