The first use of the term "microprocessor" is attributed to [[Viatron|Viatron Computer Systems]]<ref>[http://bitsavers.org/pdf/viatron/ViatronSystem21Brochure.pdf Viatron Computer Systems. "System 21 is Now!"] {{webarchive|url=https://web.archive.org/web/20110321143159/http://www.bitsavers.org/pdf/viatron/ViatronSystem21Brochure.pdf |date=2011-03-21 }} (PDF).</ref> describing the custom integrated circuit used in their System 21 small computer system announced in 1968.

Since the early 1970s, the increase in capacity of microprocessors has followed [[Moore's law]]; this originally suggested that the number of components that can be fitted onto a chip doubles every year. With present technology, it is actually every two years,<ref>{{citeCite FTP journal|last=Moore |first=Gordon |title=Cramming more components onto integrated circuits |journal=Electronics |volume=38 |issue=8 |date=19 April 1965 |url=ftp://download.intel.com/museum/Moores_Law/Articles-Press_Releases/Gordon_Moore_1965_Article.pdf |access-date=2009-12-23 |url-status=dead |archive-urlserver=https://web.archive.org/web/20080218224945/http://download.intel.com/museum/Moores_Law/Articles-Press_Releases/Gordon_Moore_1965_Article.pdf |archive-date=18 February 2008Electronics }}</ref> {{Obsolete source|date=August 2019}} and as a result Moore later changed the period to two years.<ref>{{cite web |title=Excerpts from A Conversation with Gordon Moore: Moore's Law |publisher=Intel |year=2005 |url=ftp://download.intel.com/museum/Moores_Law/Video-Transcripts/Excepts_A_Conversation_with_Gordon_Moore.pdf |access-date=2009-12-23 |url-status=dead |archive-url=https://web.archive.org/web/2012102906005020080218225540/http://download.intel.com/museum/Moores_Law/Video-Transcripts/Excepts_A_Conversation_with_Gordon_Moore.pdf |archive-date=20122008-1002-2918 |url-status=dead |access-date=2009-12-23 }}</ref>
