EGA was introduced in October 1984 by IBM,<ref name=":4">High-Resolution Standard Is Latest Step in DOS Graphics Evolution, ''InfoWorld'', June 26, 1989, p. 48.</ref><ref name=":5">News Briefs, Big Blue Turns Colors, ''InfoWorld'', October 8, 1984.</ref> shortly after its new [[IBM Personal Computer AT|PC/AT]]. The EGA could be installed in previously released IBM PCs, but required a [[Read-only memory|ROM]] upgrade on the [[Motherboard|mainboard]].<ref>{{Cite book |url=https://ibm.retropc.se/ibm_ega/IBM%20EGA%20-%20Installation%20Instructions.pdf |title=IBM EGA Installation Instructions |year=1984 |pages=1 |access-date=2020-08-15 |archive-date=2022-02-11 |archive-url=https://web.archive.org/web/20220211184437/https://ibm.retropc.se/ibm_ega/IBM%20EGA%20-%20Installation%20Instructions.pdf |url-status=dead }}</ref>

[[Chips and Technologies]]' first product, announced in September 1985, was a four-chip EGA [[chipset]] that handled the functions of 19 of IBM's proprietary chips on the original Enhanced Graphics Adapter. By that November's [[COMDEX]], more than a half dozen companies had announced EGA-compatible boards based on C&T's chipset.<ref name="EGS">[https://books.google.com/books?id=a91QXlvTPHAC&pg=PA140 The Enhanced Graphics Standard Comes of Age], ''[[PC Magazine]]'', August 1986.</ref> The first EGA-compatible board was Vega in December 1985, released by [[Video Seven]] and using C&T's chipset.<ref name=ega>{{cite journal | last=Bermant | first=Charles | date=February 11, 1986 | url=https://books.google.com/books?id=yCeTeDMBhg8C&pg=PA34 | title=EGA Standard Evolves for PC Graphics Users | work=PC Magazine | publisher=Ziff-Davis | volume=5 | issue=3 | pages=33–34 | via=Google Books | access-date=February 20, 2024 | archive-date=February 20, 2024 | archive-url=https://web.archive.org/web/20240220094029/https://books.google.com/books?id=yCeTeDMBhg8C&pg=PA34 | url-status=live }}</ref>{{rp|34}} The Vega was half the length of the original IBM EGA board.<ref name=race>{{cite journal | last=Clark | first=Don | date=April 23, 1987 | url=https://www.proquest.com/docview/302120522/ | title=IBM Signals a New Race for Video-7 | work=The San Francisco Chronicle | page=33 | via=ProQuest}}</ref>

Between 1984 and 1987, several third-party manufacturers produced [[Computer compatibility|compatible]] cards, such as the ''Autoswitch EGA''<ref name=":0">{{Cite news |last=Kallenbach |first=Rolf |date=July 28, 1986 |title=Paradise EGA Makes Switching Automatic |pages=53 |work=InfoWorld |url=https://books.google.com/books?id=Vy8EAAAAMBAJ&q=infoworld+enhanced+%22EGA%22&pg=PA53}}</ref> or [[Genoa Systems]]' ''Super EGA'' chipset.<ref>{{Cite news |last=Brownstein |first=Mark |date=February 23, 1987 |title=Genoa Systems Ready to Ship $449 Half-Size Graphics Card |pages=16 |work=InfoWorld |url=https://books.google.com/books?id=1DAEAAAAMBAJ&q=Genoa+Systems+Ready+to+Ship+%24449+Half-Size+Graphics+Card%2C+InfoWorld%2C+February+23%2C+1987&pg=PA16}}</ref> Later cards supporting an extended version of the VGA were similarly named [[Super VGA]].

The EGA standard was made obsolete in 1987 by the introduction of [[Multi-Color Graphics Array|MCGA]] and VGA with the [[IBM PS/2|PS/2]] computer line.<ref>Scott Mueller, ''Upgrading and Repairing PCs, Tenth Edition'', Que, 1998, 0-7897-1636-4, page 515.</ref>
