→Market impact: Moved 'ITV Micro' to end of section, after all items about the BBC Micro itself. This is easily the least significant item in the section and its revised position reflects this, rather than top of the list. |

The '''British Broadcasting Corporation Microcomputer System''', or '''BBC Micro''', is a series of [[microcomputer]]s designed and built by [[Acorn Computers]] Limited in the 1980s for the [[Computer literacy|Computer Literacy]] Project of the [[BBC]]. Designed with an emphasis on education, it was notable for its ruggedness, expandability, and the quality of its [[operating system]].{{citation needed|date=December 2023}} The machine was the focus of a number of educational BBC TV programmes on computer literacy, starting with ''[[The Computer Programme]]'' in
After the Literacy Project's [[call for bids]] for a computer to accompany the [[television programmes]] and literature, Acorn won the contract with the ''Proton'', a successor of its [[Acorn Atom|Atom]] computer prototyped at short notice. Renamed the BBC Micro, the system was adopted by most [[schools in the United Kingdom]], changing Acorn's fortunes. It was also successful as a [[home computer]] in the UK, despite its high price compared to some other home computers sold in the UK at the time. Acorn later employed the machine to simulate and develop the [[ARM architecture]].

During the early 1980s, the BBC started what became known as the ''BBC Computer Literacy Project''.<ref>John Radcliffe and Roberts Salkeld (1983), [https://clp.bbcrewind.co.uk/media/Towards%20Computer%20Literacy.pdf Towards Computer Literacy - The BBC Computer Literacy Project 1979-1983], BBC Education.<br /> [http://www.naec.org.uk/organisations/bbc-computer-literacy-project/towards-computer-literacy-the-bbc-computer-literacy-project-1979-1983 HTML version], National Archive of Educational Computing. Accessed 2024-01-29</ref> The project was initiated partly in response to an [[ITV (TV network)|ITV]] documentary series ''The Mighty Micro'', in which [[Christopher Evans (computer scientist)|Christopher Evans]] of the UK's [[National Physical Laboratory (United Kingdom)|National Physical Laboratory]] predicted the coming [[microcomputer revolution]] and its effect on the economy, industry, and lifestyle of the United Kingdom.<ref name="LEM">{{cite web |last=Hormby |first=Thomas |title=Acorn and the BBC Micro: From education to obscurity |work=Low End Mac |date=8 February 2007 |url=http://lowendmac.com/2007/acorn-and-the-bbc-micro-from-education-to-obscurity/ |access-date=1 March 2007 |archive-url=
The BBC wanted to base its project on a [[microcomputer]] capable of performing various tasks which they could then demonstrate in the TV series ''[[The Computer Programme]]''. The list of topics included [[computer programming|programming]], [[computer graphics|graphics]], sound and music, [[teletext]], controlling external hardware, and [[artificial intelligence]]. It developed an ambitious specification for a BBC computer, and discussed the project with several companies including [[Acorn Computers]], [[Sinclair Research]], Newbury Laboratories, [[Tangerine Computer Systems]], and [[Dragon Data]].<ref name="LEM"/>

In 2013, NESTA released a [https://www.nesta.org.uk/report/the-legacy-of-bbc-micro/ report into the legacy of The BBC Micro], looking at the history and impact of the machine and The BBC Computer Literacy project.

The BBC Micro had a lasting technological impact on the education market by introducing an informal educational standard around the hardware and software technologies employed by the range, particularly the use of BBC BASIC, and by establishing a considerable investment by schools in software for the machine. Consequently, manufacturers of rival systems such as [[IBM PC compatible]]s (and almost-compatibles such as the [[RM Nimbus]]), the [[Apple Inc.|Apple]] [[Macintosh]], [[Commodore International|Commodore]] [[Amiga]], and Acorn as manufacturer of the BBC Micro's successor, the Archimedes, were compelled to provide a degree of compatibility with the large number of machines already deployed in schools.<ref name="acornuser198911_auntie">{{cite magazine |
