The jumbotron was invented in Japan during the early 1980s, but there is a dispute between two rival Japanese companies, [[Mitsubishi Electric]] and [[Sony]], over its invention.<ref name="sbnation">{{cite web |last1=Pilon |first1=Mary |title=Twilight of the Jumbotron, the biggest invention in sports |url=https://www.sbnation.com/2015/11/11/9703912/twilight-of-the-jumbotron |website=[[SB Nation]] |publisher=[[Vox Media]] |access-date=27 September 2019 |date=11 November 2015}}</ref> In 1980, Mitsubishi introduced the first large-scale video board,<ref name="Nelson">{{cite book |last1=Nelson |first1=Murry R. |title=American Sports: A History of Icons, Idols, and Ideas [4 volumes]: A History of Icons, Idols, and Ideas |date=2013 |publisher=[[ABC-CLIO]] |isbn=9780313397530 |page=653 |url=https://books.google.com/books?id=tfTXAQAAQBAJ&pg=PA653}}</ref> the [[Diamond Vision]], which was a large screen using [[cathode-ray tube]] technology similar to traditional tube [[television]]s.<ref name="sbnation"/> The first demonstration of the technology was during the [[1980 Major League Baseball All-Star Game]] in [[Dodger Stadium]], [[Los Angeles]].<ref name="Nelson"/>

Panasonic had the Astro Vision which was based on Fluorescent Discharge Tubes. These were the only three players in the large-screen industry.

In 1985, the term "JumboTron" was coined by Sony for its large-scale video board.<ref name="Nelson"/> The JumboTron was the brand name for the large-scale video boards originally manufactured by Sony and is recognized as one of the largest non-projection video displays ever manufactured. Sony creative director [[Yasuo Kuroki]], who previously helped create the [[Walkman]], is credited with the development of the JumboTron.<ref name="sbnation"/> It was introduced at the [[Expo '85]] held in May 1985 at [[Tsukuba, Ibaraki]]. It had a [[display resolution]] of 450,000 [[pixels]], using a new proprietary Sony technology called the Trini-lite.<ref name="Popular">{{cite journal |last1=Fisher |first1=Arthur |title=Science Newsfront |journal=[[Popular Science]] |date=May 1985 |volume=226 |issue=5 |page=10 |url=https://books.google.com/books?id=iwAAAAAAMBAJ&pg=PA10 |publisher=[[Bonnier Corporation]] |issn=0161-7370}}</ref> It was a [[microprocessor]]-based light bulb developed by one of Kuroki's colleagues, chief [[Betamax]] engineer Yuji Watanabe. Trini-lite technology allowed screen clarity and [[computer]] control, laying the foundation for the first Sony Jumbotrons.<ref name="sbnation"/>

In December 1986, the [[San Antonio Spurs]] unveiled the first indoor arena JumboTron scoreboard at the now-defunct [[HemisFair Arena]].<ref>{{Cite web |last=Rodriguez |first=Ken |date=2017-04-22 |title=Introduced by the Spurs, the JumboTron Marks a Sports Arena Milestone |url=http://sanantonioreport.org/introduced-by-the-spurs-the-jumbotron-marks-a-sports-arena-milestone/ |access-date=2022-09-09 |website=San Antonio Report |language=en-US}}</ref>

While the JumboTron and similar large-screen displays are physically large, they ranged from low to medium display resolutions. While the original Sony JumboTron in 1985 had a 450,000-pixel resolution, comparable to [[standard-definition television]]s of that era,<ref name="Popular"/> certain later models had lower resolutions. The JumboTron at the now-demolished [[Tampa Stadium]] in [[Tampa, Florida]], measured 30&nbsp;ft (9 m) diagonally, with a resolution of only 240x192 [[Pixel|pixels]], below [[VHS]] resolution. Screen size since then varies depending on the venue. The display introduced in 1985 was 40 meters wide by 25 meters tall. Newer, [[LED display|LED-based large screens]] have resolutions that are an order of magnitude greater than the early JumboTron resolution at a fraction of the cost. For example, the much publicized center-hung video board in the [[Dallas Cowboys]]' [[AT&T Stadium]] is 72 feet tall and 160 feet wide (22 m x 49 m), displaying HDTV at 1920 x 1080 resolution, 45 times more pixels.

The largest JumboTron in use was located at SkyDome (now [[Rogers Centre]]) in [[Toronto]], Ontario, and measured 10 m tall by 33.5 m wide (33&nbsp;ft&nbsp;×&nbsp;110&nbsp;ft), with a resolution of 672 × 200 pixels, or 134,400 pixels.<ref>{{cite book |last1=Filey |first1=Mike |title=Like no other in the world: the story of Toronto's Skydome |date=1989 |publisher=Sun Controlled Ventures |location=Toronto |isbn=0-919233-31-7 |page=112}}</ref> Its cost was [[USD|US$]]17 million; by comparison, a similar-sized LED system sold today would cost around $3 million. The Rogers Centre JumboTron was replaced in 2005 by a [[Daktronics]] ProStar as part of a stadium revitalization project.

Sony JumboTron was the first video board ever in Times Square. It remained that way for almost ten years.
