Note: The Penske Entertainment editorial staff is looking back at the 10 biggest moments of 2023 in the NTT INDYCAR SERIES in this year-end series, with one installment appearing on the site per day in countdown fashion from Dec. 22-31.

In an era of flat or declining TV viewership across many sporting leagues, the NTT INDYCAR SERIES once again delivered in key metrics across the 2023 season.

Between the long-awaited documentary series, “100 Days To Indy,” that aired on The CW and then seeing increased ratings on NBC Sports in 2023, the NTT INDYCAR SERIES enjoyed increasing attention on its exciting competition.

The 17-race schedule was the most-watched season since 2011. This marked the third consecutive year of viewership growth, including the most-streamed NTT INDYCAR SERIES season on record on Peacock.

Headlined by Alex Palou’s second career series championship and Josef Newgarden’s victory in the Indianapolis 500 presented by Gainbridge, the season averaged a Total Audience Delivery (TAD) of 1.32 million viewers across NBC, USA Network, Peacock and NBC Sports digital platforms. Last year, the then-record viewership averaged 1.30 million viewers.

Half of the season’s 16 races on television delivered a TAD of more than 1 million viewers, tying last year for the highest mark since 2008. NBC’s 13 races posted a TAD of 1.47 million viewers, up 4 percent from last year’s coverage on NBC (1.42 million, 14 races).

Overall viewership was led by the 107th Running of the Indianapolis 500, which delivered a TAD of 4.93 million viewers across NBC and Peacock. The race also had a 13 share – the percentage of homes watching television at the time of the race – its best performance in 15 years. The 2008 race also achieved a 13 share.

The “100 Days to Indy” docuseries in the spring also created new fans of the series and helped drive viewership for the 107th Running of the Indianapolis 500.

Produced by Penske Entertainment and VICE Media Group, the six-part series took fans behind the scenes to chronicle the bold and brash personalities of the NTT INDYCAR SERIES as they began the 2023 season and started their epic quest for racing’s greatest prize.

The compelling docuseries was produced by multiple award-winning VICE World News, with Emmy Award-winning Patrick Dimon directing and Bryan Terry executive producing for VICE. The series had fast re-air on VICE TV and was supported across VICE’s global social media channels.

Between all the early-season fireworks that came to a head with Pato O’Ward and Scott Dixon’s dramatic collision at Long Beach and their subsequent “chat,” as well as Romain Grosjean and Scott McLaughlin’s collision and spat in St. Pete, the documentary delivered.
