Editing Box office (section)

====Dawn of modern film industry====
In the late 1960s, ''Variety'' used an [[IBM 360]] computer to collate the grosses from their weekly reports of 22 to 24 U.S. cities from January 1, 1968. The data came from up to 800 theatres which represented around 5% of the U.S. cinema population at the time but around one-third of the total U.S. box office grosses. In 1969, ''Variety'' started to publish a list of the top 50 grossing films each week.<ref>{{cite magazine|title=Computerized B.O.

In 1974, Nat Fellman founded Exhibitor Relations Co., the first company set up to track box office grosses, which it collected from the studios.<ref name=open>{{cite book|first1=Dade|last1=Hayes|first2=Jonathan|last2=Bing|title=Open Wide: How Hollywood Box Office Became a National Obsession|url=https://archive.org/details/openwidehowholly00haye|url-access=registration|publisher=Miramax Books|year=2004|isbn=1401352006|pages=[https://archive.org/details/openwidehowholly00haye/page/295 295]–7}}</ref> Two years later, Marcy Polier, an employee of the Mann theater chain, set up Centralized Grosses to collate U.S. daily box office data on a centralized basis from theaters rather than each theater chain collating their own numbers from other theater chains. The company later became National Gross Service then Entertainment Data, Inc. (EDI).<ref>{{Cite book |last=Benson-Allott |first=Caetlin |title=Killer Tapes and Shattered Screens: Video Spectatorship from VHS to File Sharing |publisher=[[University of California Press]] |year=2013 |isbn=9780520954496 |page=[https://books.google.com/books?id=jdIkDQAAQBAJ&pg=PA149 149]}}</ref>

Except for disclosures by the studios on very successful films, total domestic (U.S. and Canada) box office gross information for films was not readily available until National Gross Service started to collate this data around 1981. The collation of grosses led to wider reporting of domestic box office grosses for films. Arthur D. Murphy, a former [[U.S. Navy]] lieutenant at ''Variety'' was one of the first to organize and chart that information and report it in a meaningful form.<ref name=Murfexit>{{cite web|archive-url=https://web.archive.org/web/20031115050806/http://www.simesite.net/muggs.asp?articleid=311|url=http://www.simesite.net:80/muggs.asp?articleid=311|title=Art Murphy Exits|website=Simesite|last=Berkshire|first=Geoffrey|date=June 18, 2003|archive-date=November 15, 2003|access-date=July 5, 2020|url-status=dead}}</ref> During the 1980s, Daily ''Variety'' started to publish a weekly chart of the domestic box office grosses of films collated from the studios as compared to the Top 50 chart in ''Variety'' which was based on a sample of theatre grosses from key markets.

Gradually the focus of a film's performance became its box office gross rather than the rentals that ''Variety'' continued to report annually. Prior to the tracking of these grosses, domestic or worldwide box office grosses is not available for many earlier films so the only domestic or worldwide data available is still often the rental figures.

Murphy started to publish ''Art Murphy's Box Office Register'' annually from 1984 detailing U.S. box office grosses.<ref name=Murfexit/>

In 1984, EDI started to report Canadian grosses as well and by 1985 was reporting data for 15,000 screens. In 1987, EDI set up a database of box office information which included data on certain films back to 1970. By 1991, all U.S. studios had agreed to share their complete data reports with EDI.<ref>{{cite magazine|title=Number's Game|first=Andrew|last=Hindes|magazine=[[Variety (magazine)|Variety]]|date=November 18, 1996|page=43}}</ref> By then box office results were publicized, with ''[[Entertainment Tonight]]'' segments on the weekend's top films, increasing public discussion of poorly performing films.<ref name="mcclintock20201023">{{Cite magazine |last=McClintock |first=Pamela |date=2020-10-23 |title=Skipping Theaters?

By the 1990s, ''Daily Variety'' started to report studio's weekend estimates from Sundays on Monday mornings which led to other media reporting the data earlier.<ref name=open/> When ''[[Entertainment Weekly]]'' was launched in 1990 it started to publish the top 10 box office weekend lists from Exhibitor Relations and the company was also supplying box office data to companies such as the ''[[Los Angeles Times]]'', [[CNN]] and the [[Associated Press]].<ref name=open/>

In 1994, ''Variety'' published their first annual global box office chart showing the top 100 grossing films internationally for the prior year.<ref>{{cite magazine|magazine=[[Variety (magazine)|Variety]]|date=January 3, 1994|page=1|last=Klady|first=Leonard|title=Top 100 pix take $8 bil globally|url=https://variety.com/1994/film/news/int-l-top-100-earn-8-bil-117102/|access-date=October 4, 2019|archive-date=July 27, 2020|archive-url=https://web.archive.org/web/20200727104121/https://variety.com/1994/film/news/int-l-top-100-earn-8-bil-117102/|url-status=live}}</ref>

On August 7, 1998, Box Office Mojo was launched by Brandon Gray and in 1999 he started posting the Friday grosses sourced from Exhibitor Relations so that they were publicly available for free online on Saturdays<ref name=open/> and posted the Sunday estimates on Sundays.<ref>{{cite web|url=http://www.boxofficemojo.com/|title=Brandon Gray's Box Office Mojo|access-date=May 3, 2020|date=October 7, 1999|website=[[Box Office Mojo]]|archive-url=https://web.archive.org/web/19991008185322/http://www.boxofficemojo.com/|archive-date=October 8, 1999|url-status=dead}}</ref> In July 2008, Box Office Mojo was purchased by [[Amazon (company)|Amazon.com]] through its [[subsidiary]], [[IMDb]].<ref name=techflash>{{cite web|url=https://www.bizjournals.com/seattle/blog/techflash/2008/12/Amazons_IMDb_movie_trivia_site_acquires_rival_Box_Office_Mojo36320174.html|title=Amazon's IMDb movie trivia site acquires rival Box Office Mojo|access-date=June 17, 2018|author=Eric Engleman|date=December 17, 2008|publisher=American City Business Journals|work=TechFlash|archive-url=https://web.archive.org/web/20180701131740/https://www.bizjournals.com/seattle/blog/techflash/2008/12/Amazons_IMDb_movie_trivia_site_acquires_rival_Box_Office_Mojo36320174.html|archive-date=July 1, 2018|url-status=live}}</ref><ref name=variety>{{cite magazine|url=https://variety.com/2008/digital/markets-festivals/imdb-links-up-with-box-office-mojo-1117997423/|title=IMDB links up with Box Office Mojo|access-date=December 17, 2008|author=Ben Fritz|date=December 15, 2008|magazine=[[Variety (magazine)|Variety]]|archive-date=December 19, 2008|url-status=live|archive-url=https://web.archive.org/web/20081219095923/http://www.variety.com/article/VR1117997423.html?categoryid=18&cs=1}}</ref>
