PBS' long-running documentary series American Masters has been an Emmys staple since the 1998 category restructuring. Out of 23 years, American Masters only missed being nominated three times. And out of those 20 nominations, it's won 10. This season looks to be another favorite, with episodes on Ursula K. Le Guin, Miles Davis, Mae West, and Toni Morrison.

You can stream all episodes of American Masters via the PBS Documentaries channel on Prime Video, or via PBS Passport, Public Television's streaming service that comes with membership.

Also nominated in Outstanding Documentary or Nonfiction Series, Hillary is one of the most intimate portraits of the former first lady and secretary of state Hillary Rodham Clinton ever assembled. It traces her life from an early feminist to one of the most polarizing, beloved/reviled figures in modern politics. The four-part series was already nominated for the TCA Award for Outstanding Achievement in News and Information.

Hillary is available to stream via Hulu.

The last of the Outstanding Documentary or Nonfiction Series noms is McMillion$, HBO's deep dive into the Monopoly promotion scam in the 1990s era. Perpetrated by Jerry Jacobson, the scheme wound up encompassing a shockingly wide range of people, including fake winners.

The documentary series is nominated for five Emmys altogether, including Outstanding Writing for Nonfiction Programming and three Nonfiction technical categories of Outstanding Music Composition, Picture Editing, and Sound Editing.

Initially planned as a theatrical release, but canceled due to the coronavirus pandemic, Beastie Boys Story wound up streaming on Apple TV+.

Unlike the first two in the Outstanding Documentary or Nonfiction Special, The Great Hack is not specifically about famous people. It's instead a documentary film about the Facebook–Cambridge Analytica data scandal, breaking down British investigative journalist Carole Cadwalladr's uncovering of how badly social media was hiding the exploitation of users and how Facebook affected the 2016 Brexit campaign.

Produced by Oscar nominees Jehane Noujaim and Karim Amer, The Great Hack is currently streaming on Netflix.

It may not have been nominated in the top Documentary category or Outstanding Directing, but Leah Remini: Scientology and the Aftermath did land Outstanding Hosted Nonfiction Series or Special for the second year running. The deep dive into exposing Scientology was beaten by Anthony Bourdain's posthumous win for Parts Unknown, but with Season 3, it could get lucky.

All three seasons of Leah Remini: Scientology and the Aftermath are streaming on Hulu.

While Outstanding Hosted Nonfiction Series or Special is also the home of less documentary-oriented shows like Comedians in Cars Getting Coffee and The World According to Jeff Goldblum, it also had Ugly Delicious, the best documentary about food on Netflix, IMO. Hosted by the charming David Chang of Momofuku fame, this exploration into the history of some of the world's famous and favorite dishes is a lesson in culture and history.

Both seasons of Ugly Delicious are streaming on Netflix.

Nominated for Outstanding Directing for a Documentary/Nonfiction Program, The Cave, directed by Feras Fayyad, is a Syrian-Danish documentary film produced by National Geographic.

Unlike the others on this list, American Factory is not an interview-heavy documentary, but rather a "fly on the wall" telling of the takeover of the shuttered Moraine Assembly, once a General Motors plant, by Chinese company Fuyao Glass Industry Group Co., which makes construction and automobile glass. Like The Cave, this Outstanding Directing for a Documentary/Nonfiction Program nominee was an Oscar nominee earlier this year. It is also nominated for Outstanding Cinematography and Picture Editing in Nonfiction.

American Factory is available to stream on Netflix.
