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 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 (the first year in which the race was carried under the ESPN on ABC branding), the race was first aired in 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.
