Editing Indianapolis 500 (section)

===Race name===
The race was originally advertised as the "International 500-Mile Sweepstakes Race"<ref name="INDY3" /> from 1911 to 1916. However, from its inception, the race has been widely known as the Indianapolis 500 or, more simply "the 500", as for many years, it was the only noteworthy auto race of such distance. In 1919, the race was referred to as the "Liberty Sweepstakes" following [[World War I|WWI]].<ref name="INDY8">{{cite news|date=May 6, 1919|title=Limit Auto Race Entries: Only Thirty-Three Drivers to Start in Indianapolis Sweepstakes|newspaper=[[The New York Times]]|url=https://www.nytimes.com/1919/05/06/archives/limit-auto-race-entries-only-thirtythree-drivers-to-start-in.html|access-date=2015-05-28|archive-date=July 26, 2018|archive-url=https://web.archive.org/web/20180726013453/https://www.nytimes.com/1919/05/06/archives/limit-auto-race-entries-only-thirtythree-drivers-to-start-in.html|url-status=live}}</ref> From 1920 to 1980, the race officially reverted to the "International Sweepstakes" moniker, as printed on the tickets and other paraphernalia, with slight variations over the years.

Following [[World War II|WWII]], the race was commonly recognized as "The 500", "The 500-Mile Race", "Indianapolis 500-Mile Race", "Indianapolis 500", or the simple form "Indy 500". Usually the [[Ordinal numeral|ordinal]] (e.g. "50th") preceded it. Often the race was also advertised on the radio as the "Annual Memorial Day race", or similar variations. By the late 20th century, the term "Indy 500" had slowly emerged as the most common and most popularly used moniker. As such, since 2016, the official race logo has used the contemporary and colloquial term "Indy 500".

For the [[1981 Indianapolis 500|1981 race]], the name "65th Indianapolis 500-Mile Race" was officially adopted, with all references as the "International Sweepstakes" dropped. Since 1981, the race has been formally advertised in this fashion, complete with a unique annual logo with the ordinal almost always included. Around that same time, in the wake of the [[1979 Indianapolis 500|1979]] entry controversy, and the formation of [[Champ Car|CART]], the race changed to an invitational event, rather than an [[Open (sport)|Open]], rendering the "[[sweepstakes]]" description inappropriate.

For nearly a century, the race eschewed any sort of [[naming rights]] or [[Sponsor (commercial)|title sponsor]], a move, though uncommon in the modern sports world, that was well received by fans. This tradition finally ended in [[2016 Indianapolis 500|2016]] when a presenting sponsor, PennGrade, was added for the first time. In the 21st century, the facility has also slowly added sponsorship ads on the retaining walls and infield grass. The ESPN-produced ABC telecast of the event did not recognize this sponsorship and instead had [[Firestone Tires]] as its presenting sponsorship.<ref>{{Cite web|title=ABC's 54th Indianapolis 500 Telecast Bringing Consecutive Streak to Close|url=https://espnmediazone.com/us/press-releases/2018/05/abcs-54th-indianapolis-500-telecast-bringing-consecutive-streak-to-close/|access-date=2018-05-28|website=ESPN MediaZone|date=23 May 2018|language=en-US|archive-date=May 28, 2018|archive-url=https://web.archive.org/web/20180528134255/https://espnmediazone.com/us/press-releases/2018/05/abcs-54th-indianapolis-500-telecast-bringing-consecutive-streak-to-close/|url-status=live}}</ref>
