{{Short description|American computer graphics company}}
'''ColorGraphics Weather Systems''' was a [[computer graphics]] company that pioneered the use of computer graphics for displaying [[weather forecast]]s on local [[television]].<ref name=Nelson303/> Formed in 1979 by Terry Kelly and Richard Daly, it is now part of [[Weather Central]], another of Kelly's companies.

Line 10 ⟶ 11:
Kelly's idea was to adapt the McIdas concept for lower cost [[home computer]] systems that were appearing in the late 1970s. Their first system, "LiveLine", was based on the [[Apple II]].<ref name=Nelson303/> Its graphics system could not be [[genlock]]ed, so a TV camera had to be pointed at the screen to send the video into the production systems. This initial system was soon replaced by a similar one running on [[Cromemco]] computers using a modified version of their [[Cromemco Dazzler|Dazzler]] color-graphics card.<ref>Robert Kuhmann, [http://www.retrotechnology.com/herbs_stuff/crom_kuh.html "Cromemco S-100 computer ~ a Silicon Valley memoir (1977–1997)"], January 2008</ref> In spite of its simplicity and low resolution, the fast production and "high tech" look caught on, and by the mid-1980s the system was almost universal, replacing [[Chroma key|bluescreen]] systems on cardboard maps that had previously been used.<ref name=Nelson303>{{harvnb|Nelson|2007|page=303}}</ref> The company noted that 70% of the top 50 TV markets were using the system by 1982.<ref name=wxc>{{cite web|url=http://www.wxc.com/corporate/history.html |title=Weather Central History |archive-url=https://web.archive.org/web/20081214165028/http://www.wxc.com/corporate/history.html |archive-date=December 14, 2008 }}</ref> By 1984 80% of all television stations in the country were using ColorGraphics system, built on Cromemco microcomputers, to generate weather, news, and sports graphics.<ref>{{cite magazine |last1=Melton |first1=Louise |title=Video Processing |magazine=Computers & Electronics |date=November 1984 |volume=22 |issue=11 |page=96 |url=https://archive.org/details/ComputersElectronics/ComputersElectronics1984-11/page/n91/mode/2up |quote=Some 80% of all the television stations in the country use Colorgraphics’s LiveLine systems to generate weather, news and sports graphics. The basic system is built around Cromemco microcomputers}}</ref>
In 1982 the company was purchased by [[Dynatech|Dynatech Corporation]], an expanding electronics company. Dynatech purchased [[Cromemco]] in 1987 and rolled the two companies together, before divesting all of its media properties in the early 1990s. Kelly and Daly purchased the rights back from Dynatech in 1994, operating under the Weather Central name. In 1995 they introduced the new "GENESIS" platform on [[Silicon Graphics]] computers, which later moved onto [[Hewlett-Packard]] workstations.<ref name=wxc/>
