Centennial Era

In 2009, the Indianapolis Motor Speedway began a three-year-long "Centennial Era" to celebrate the 100th anniversary of the opening of the track (1909), and the 100th anniversary of the first Indy 500 (1911). As a gesture to the nostalgic ''Centennial Era'' celebration (2009–2011), tickets for the 2009 race donned the moniker "93rd 500 Mile International Sweepstakes". It is the first time since 1980 that the "Sweepstakes" title has been used. In May 2009, the ordinal (93rd) was used very sparingly, and for the first time since 1981, was not identified on the annual logo. Instead, in most instances in print, television, and radio, the race was referred to as the "2009 Indianapolis 500". Since the race was not held during the United States' participation in the two World Wars (1917–1918, 1942–1945), the advertised Centennial Era occurred during the 93rd to 95th runnings. To avoid confusion between the 100th anniversary, and the actual number of times the race has been run, references to the ordinal during the ''Centennial Era'' were curtailed. In the

Race name

The race was originally advertised as the "International 500-Mile Sweepstakes Race" from 1911 to 1916. However, from its inception, the race has been widely known as the Indianapolis 500 or, more simply as "the 500". In 1919, the race was referred to as the "Liberty Sweepstakes" following

, 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 (e.g. "50th") preceded it. Often the race was also advertised on the radio as the "Annual Memorial Day race," or similar variations. For the 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

Field

The traditional 33-car starting field at Indianapolis is larger than the fields at the other IndyCar races. The field at Indy typically consists of all of the full-time IndyCar Series entries (roughly 20–22 cars), along with roughly 10–15 part-time or "Indy-only" entries. The "Indy-only" entries, also known as "One-offs", may be an extra car added to an existing full-time team, or a part-time team altogether that does not enter any of the other races, or enters only a few selected races. The "Indy-only" drivers may come from a wide range of pedigrees but are usually experienced Indy car competitors who either lack a full-time ride, are former full-time drivers who have elected to drop down to part-time status, or occasional one-off drivers from other racing disciplines. It is not uncommon for some drivers (particularly former Indy 500 winners) to quit full-time driving during the season, but race solely at Indy for numerous years afterward before entering full retirement.

. Rules are generally the same as every other IndyCar race. In the past, particularly during the era in which USAC sanctioned the Indy 500 (but CART sanctioned the other Indy car races), rules at Indy slightly differed at times. The result, for example, would be a particular chassis or engine configuration being legal at Indy, but not so at the CART-sanctioned events. This was rather commonplace in the 1980s and early 1990s, when "stock-block" engines (namely the V-6 Buick) were allotted an increased level of turbocharger boost by USAC at Indy, compared to the purpose-built V-8 quad-cam engines. While the "stock block" engines were technically legal in CART competition, they were not given the increased boost advantage, which effectively rendered them uncompetitive, and precluded their use by teams. The most famous manifestation of the USAC rules disparity was the

. Teams may enter up to two machines under a given car number—the "primary" car and a "backup" car. The backup car is identified by the letter "T". For example, the two cars for the #2 team would be numbered #2 and #2T. Both cars may be practiced during the month, but due to engine lease rules, they must share the same engine. It is not uncommon for teams to prefer their backup car, if it is deemed faster, or for other strategic reasons. Additionally, as the month wears on, a "T car" may be split off into a separate entry, and reassigned a new number, or be sold to another team. All cars must pass a rigorous technical inspection before receiving a sticker signifying that the car is eligible to practice. Various criteria include minimum weight, dimensions, and approved parts, particularly safety equipment. Before and after qualification attempts, cars must pass another inspection. The pre-qualifying inspection is focused on safety aspects and is done on the pit lane qualifying queue. It is relatively brief, due to the time constraints of the qualifying procedure. The post-qualifying inspection is much more stringent and lengthy, taking place in the garage area. It is to detect deviations from the performance guidelines set forth by the league, and cars can and have been fined or outright disqualified if they fail inspection. During the race, work on the car is permitted, but it is usually limited to routine pit stop work (changing tires and refueling) and minor adjustments (wing angles, etc.) Pit stop activity is rigorously rehearsed by the crews and in modern times, routine pits stops are regularly completed in under ten seconds. Other more involved work, such as replacing damaged bodywork (wings, nose cones, etc.), can also be completed quickly by the crews. More lengthy repairs are allowed, and since 1998 teams are permitted to return to the garage area to make repairs. However, there are limitations to the extent of repair work allowed and the practicality of such work. Teams are not allowed to change engines, and since 1933 a rule has been in place where teams are not allowed to add

Qualifying procedure

Throughout the years, the race has used several different qualifying procedures. The current four-lap (ten-mile) qualifying distance was first introduced in 1920 and has been used every year since 1939.Mittman, Dick
Indianapolis 500 Qualifying Has Evolved Over The Years
, Indy500.com, September 22, 2004
Presently, qualifying occurs on over two days. On Day 1, positions 13-30 (or 13-33 if there are only 33 entries) have their position set with all other positions set on Day 2. Following Fast Friday practice, all cars are entered into a blind draw for the qualifying order. *Saturday: All entries are guaranteed at least one attempt to qualify and can make additional attempts if time permits. At the end of the session, the fastest twelve drivers advance to a "shootout" session held on the next day to determine pole position and the first four rows of the grid. As mentioned above, drivers who qualify 10th-30th have their spots locked in and will not re-qualify. Drivers who qualify 31st and lower advance to a separate "shootout" session also held on the next day to determine the final three spots on the grid. For re-attempts, there are two lanes: Lane 2 is known as the "no risk lane" and drivers can keep their previous time if their second (or subsequent) run is slower. Lane 1 is known as the "priority lane," and no cars from lane 2 are allowed on track unless lane 1 is empty. However, to re-qualify in lane 1 you must withdraw any previous times, regardless if the attempt is slower than a previous one. *Sunday: The drivers who qualified 31st and lower from Saturday have their original times erased. There is one 75 minute session. Each driver gets one guaranteed attempt and can make additional attempts if time permits. Drivers who qualify 31st-33rd have their positions locked in. Drivers who finish 34th and lower fail to qualify. The fastest twelve drivers from Saturday take part in a second round of qualifying, with the top six advancing to the Firestone Fast Six. The qualifying order is based on the times from Saturday's session from slowest to fastest. Once again, the times from Saturday are erased and each driver is given only one attempt, locking in positions 7-12. Following a cool down period, including all cars taking slow cool down laps on track behind the pace/safety car, the remaining six drivers get one final attempt. The fastest driver wins the highly coveted pole position and the remaining five drivers have their positions locked in based on their times. For each attempt, cars are allowed two warm-up laps. At that time, a member of the team is stationed at the north end of the main stretch. He or she must wave a green flag, signaling an attempt, or else the car will be waved off. The attempt can be waved off during any of the four laps by the team, driver, or race officials. (The series will wave off the run if it is obvious the run will not be fast enough to qualify and it is getting late in the day.) If an attempt is waved off after the run starts, the attempt counts and the previous time is still forfeited unless race officials waved off the attempt because of weather. Weather can and often does affect qualifying and can result in last-minute format changes.

This effectively left eight starting positions open to the CART-regulars that chose not to participate in the IRL races and would be the first time that not all 33 spots were open for qualification in the history of the race. CART refused to compromise on the schedule conflicts, skip the IRL races required to accumulate the qualifying points,

The U.S. 500, meanwhile was marred by a crash on the pace laps that forced ten teams to use backup cars. For 1997, new rules for less expensive cars and "production-based" engines were put into place. The move made it such that the IRL utilized different and incompatible equipment from CART; no CART-based teams would enter the Indy 500 for the next three years. CART would run a 300-mile race Gateway Motorsports Park, Gateway International Raceway on the Saturday of Memorial Day weekend from 1997–1999 to avoid a conflict.

NASCAR and the 500

In the 1960s and early 1970s, the Indy 500 and the Coca-Cola 600, World 600 (now known as the Coca-Cola 600) at Charlotte Motor Speedway were held on different days of the week. A handful of

regulars participated in both events in the same year, including Bobby Allison, Donnie Allison, Cale Yarborough, and Lee Roy Yarbrough. From 1974 to 1992, the two events were scheduled for the same day and same starting time, making participation in both impossible. A few stock car drivers during that time, namely Neil Bonnett in 1979, nevertheless still attempted to qualify at Indy, even if that meant skipping Charlotte altogether.

at Charlotte Motor Speedway, Charlotte on the same day. Since 1993, the Coca-Cola 600 has been scheduled in the evening the same day as the Indy 500. The effort has been known as Double Duty (auto racing), "Double Duty". After the Indy 500, drivers would catch a helicopter directly from the Speedway to Indianapolis International Airport. From there they would fly to Concord Regional Airport, and ride a helicopter to the NASCAR race. John Andretti, Tony Stewart, and Robby Gordon attempted the feat, with Kurt Busch being the latest in 2014. In 2001, Tony Stewart became the first driver to complete the full race distance (1,100 miles) in both races on the same day. For 2005, the start of Indianapolis was pushed back to 1 p.m. Eastern Daylight Time, EDT to improve television ratings. This significantly closed the window for a driver to be able to race both events on the same day. (The race's original starting time had been set at 11 a.m. EST to 12 noon EDT—because in 1911, race promoters estimated it would take six hours to complete the event, and they did not want the race to finish too close to dinnertime. Nowadays, the race is routinely completed in under three-and-a-half hours.) Two drivers, Mario Andretti and

In 2010, Chip Ganassi became the first car owner to win the Daytona and Indianapolis 500s in the same year, with Jamie McMurray winning the Daytona 500 and Dario Franchitti winning the Indianapolis 500. In 2010, Bruton Smith (owner of Speedway Motorsports, Inc.), offered $20 million to any driver, IndyCar or NASCAR, who can win both the Indianapolis 500 and the Coca-Cola 600 on the same day starting in 2011, a feat that had never been accomplished. For 2011, the Indianapolis Motor Speedway moved the start time of the Indy 500 back to 12:15 PM EDT (prior to 2005, the engines started at 10:52 AM EST; under the modern schedule, engines start around 12:05 PM for a start around 12:15 PM), which re-opened the window for travel. Brad Keselowski suggested that he would consider answering the challenge in 2014. It was announced on March 4, 2014, that Kurt Busch would attempt to qualify for the 2014 Indianapolis 500, driving a fifth car for the Andretti Autosport team. Busch completed all 500 miles at Indy to finish sixth but dropped out of the 600 with a blown engine just past the 400-mile mark. For 2019, NBC Sports and the Speedway changed the start time. The engines started at 12:38 PM for a start time of 12:45 PM.


Culture


Memorabilia

Many people promote and share information about the Indianapolis 500 and its memorabilia collecting. The National Indy 500 Collectors Club is an independent active organization that has been dedicated to supporting such activities. The organization was established January 1, 1985, in Indianapolis by its founder John Blazier and includes an experienced membership available for discussion and advice on Indy 500 memorabilia trading and Indy 500 questions in general. The longest-running Indy racing memorabilia show is the National Auto Racing Memorabilia Show.


Entertainment

The Indianapolis 500 has been the subject of several films and has been referenced many times in television, movies, and other media.


Milk

Louis Meyer requested a glass of buttermilk after winning his second Indy 500 race in 1933. After winning his third title in 1936, he requested another glass but instead received a bottle. He was captured by a photographer in the act of swigging from the bottle while holding up three fingers to signify the third win. A local dairy company executive recognized the marketing opportunity in the image and, being unaware Meyer was drinking buttermilk, offered a bottle of milk to the winners of future races. Milk has been presented each year since then, apart from 1947 to 1955. Modern drivers are offered a choice of whole, 2%, and skim. At the 1993 Indianapolis 500, winner

, who owned and operated an orange grove, notoriously drank orange juice instead of milk during the televised winner's interview. He eventually relented and also drank from the milk bottle later in the post-race ceremonies after the broadcast was over, but the public relations damage had already been done. The snub led to Fittipaldi being booed at the next ChampCar race, the Milwaukee Mile, in Milwaukee, Wisconsin, the heart of dairy country, and by some, as late as 2008 Indianapolis 500, 2008 in which he drove the pace car.

, as a promotion, the track gave out commemorative bottles of milk to 100,000 attendees to toast the winner with milk after the race.


Female drivers

Female participation of any sort at Indianapolis was discouraged and essentially banned throughout the first several decades of competition. As such, female reporters were not even allowed in the pit area until 1971. There have been nine female drivers to qualify, starting with Janet Guthrie in 1977 Indianapolis 500, 1977. Sarah Fisher has competed nine times, the most of any woman. Danica Patrick led 19 laps in the 2005 race and ten laps in the 2011 race, the only times a woman has led laps during the race. Pippa Mann has raced in Indy five consecutive times between 2013 and 2017.


Broadcasting

Radio coverage of the race dates back to 1922. The race has been broadcast live on the radio in its entirety by the Indianapolis Motor Speedway Radio Network since 1953. The Hulmans did not allow live television coverage of the 500 until 1986, largely to maximize gate attendance. The race was briefly televised live in 1949 and 1950 on WRTV, WFBM-TV (today's WRTV), after which the practice was discontinued. From 1964 to 1970, the race was broadcast live on closed-circuit television in theaters around the country. From 1965 through 1970, a highlighted version of the race was shown on ESPN on ABC, ABC's ''Wide World of Sports (U.S. TV series), Wide World of Sports''. From 1971 through 1985, an edited same-day, tape delay (broadcasting), tape delay broadcast of the race was shown in prime time. The race broadcast was edited down to either two or three hours in duration (including commercials). From 1986 through 2018, ABC televised the race live in its entirety. However, at the request of the Speedway, Indianapolis affiliate WRTV was required to blackout (broadcasting), blackout the live broadcast and carry it on tape delay in prime time to encourage local race attendance; WRTV would air the ABC primetime lineup in the afternoon. In 2007 Indianapolis 500, 2007 (the first year in which the race was carried under the ESPN on ABC branding), the race was first aired in High-definition television, high-definition. In 2016, the IMS declared a sell-out of race tickets for the 100th running of the event, meaning that WRTV would be allowed to air the race live for the first time since 1950. Under the live coverage arrangement, the Indianapolis affiliate of the network airing the race airs that day's programming in a transposed arrangement, with network primetime programming airing during the race and transmitted to the affiliate in advance (for instance in 2019, WTHR aired the season finale of the NBC primetime series ''Good Girls (TV series), Good Girls'' at 2 p.m. local time), while the race airs on tape delay in prime time. Coverage of time trials on ABC dates back to 1961. ABC covered time trials in various live and in tape-delayed formats from 1961 to 2008 and from 2014 to 2018. ESPN (and later along with ESPN2) carried various portions of time trials from 1987 to 2008. Versus covered time trials from 2009 to 2013. Practice sessions have been streamed live online dating back to at least 2001. In 2019, coverage of the Indianapolis 500 moved to IndyCar Series on NBC, NBC, as part of a new three-year contract that unifies the IndyCar Series' television rights with NBC Sports (the parent division of its current cable partner NBCSN), and replaces the package of five races broadcast by ABC with an eight-race package on NBC. The Indianapolis 500 is one of the eight races; this contract ended ABC's 54-year tenure as broadcaster of the race. WTHR is now the local broadcaster of the race under this contract; the existing blackout policy remains, though speedway officials have left the door open to allowing WTHR to air the race live in the event of a sellout. In contrast with the usual sell-out policy, in 2020, the race aired live on WTHR, as the Speedway ran the first three meetings (NASCAR in July, the Indianapolis 500 in August, and Road to Indy in September) behind closed doors as a result of COVID-19 pandemic in Indiana, COVID-19 cases in the state (the third INDYCAR meeting, the October road course races, admitted 10,000 spectators each day). The race was also shown live in 2021 on WTHR due to the Indianapolis Motor Speedway's restricted capacity amid the ongoing COVID-19 pandemic. WPBI-TV 16.2 in Lafayette also blacks out live coverage of the race to prevent viewers from the Indianapolis market from trying to view the race in that neighboring market and airs the race in tape delay. The first day of qualifying is no longer broadcast on television, and streamed only on Comcast's OTT service.
