Before the sci-fi series “Stranger Things” premiered on Netflix, several traditional studios had already passed on it. Its creators were first-time show runners, unknown young actors were cast in lead roles, and even though the show starred kids, it was not for children.

That was nine years ago.

The 1980s-set show about a monster that wreaks havoc on fictional Hawkins, Ind., hit a chord with Netflix’s global subscribers. “Stranger Things” has since become one of the streamer’s most culturally significant shows, with its fourth season garnering 140.7 million views in its first three months and ranking third among its top English-language series. It was instrumental in growing new branches of business for Netflix, including live events, a Broadway production and inspired brands eager to partner on licensed merchandise. It became a major franchise for the platform, a chance to build a universe around its central characters and create its own version of “Star Wars.”

The show helped build Netflix’s reputation as a place that makes big bets on original ideas and, if it’s a hit, can build a large fandom for such programs with its worldwide subscriber base.

Netflix took a chance on show runner brothers Matt and Ross Duffer. The pair never imagined the series, which held its first premiere in Silver Lake at Mack Sennett Studios, would take off the way it did.

That wasn’t lost on Matt Duffer, who stood on stage at the final season premiere inside the historic TCL Chinese Theatre in Hollywood earlier this month. It was the same place “Star Wars” premiered in 1977.

“For me, as a nerd, this is a dream come true,” Duffer told the audience.

In an interview, Bela Bajaria, the chief content officer at Netflix, lauded the success of the series: “You could take a bet on an original story, and grow it to a major franchise that has massive global appeal.”

Other Netflix shows, like “House of Cards,” have certainly captured the zeitgeist before, but co-CEO Ted Sarandos said he believes “Stranger Things” stands above some previous hits.

“This was a lot closer to a ‘Star Wars’ moment,” Sarandos said speaking on stage at the “Stranger Things” final season premiere in Hollywood earlier this month. “This is a show, and these are characters that move the culture, that spawned live events and consumer products and spinoffs and sequels … Everything from the first episode of the first season to ‘The First Shadow,’ the Broadway show, the origin story of the Upside Down, it has been and continues to be a remarkable addition to entertainment culture.”

The four past seasons of “Stranger Things” made it into Netflix’s Top 10 this past week, Netflix said. From 2020 to the second quarter of 2025, “Stranger Things” earned more than $1 billion in global streaming revenue for Netflix and was responsible for more than 2 million new subscriber acquisitions, according to estimates from Parrot Analytics, which tracks streaming data. Netflix declined to comment on Parrot’s estimates.

“Every single streaming service needs that anchor series that drives customer acquisition and helps define the original programming,” said Brandon Katz, director of insights and content strategy at Greenlight Analytics, adding for Hulu it was “The Handmaid’s Tale” and for Disney+, “The Mandalorian.” “’Stranger Things’ has undoubtedly been that for Netflix. Every few years that it does air, Netflix knows there is a guaranteed high ceiling of acquisition, retention and viewership power,” Katz said.

“Stranger Things” also helped Netflix expand into licensed goods, with brands eager to partner with the platform. There are themed Eggo breakfast foods, Lego sets and clothing.

The series “has been a catalyst for Netflix to explore all of the ways in which a single entertainment property can be turned into an entire global lifestyle,” said Robert Thompson, director of the Bleier Center for Television and Popular Culture at Syracuse University.

Its popularity has helped other creative collaborators as well.

Artists whose songs were featured on the show climbed the charts. Kate Bush’s “Running Up That Hill” was featured in Season 4 and reached No. 1 on the Billboard Global 200 and No. 4 on the Billboard Hot 100, 37 years after its original release, Netflix said. Metallica’s 1986 song “Master of Puppets” also broke the U.K. Top 30 for the first time after it played during the Season 4 finale, the streamer added.

The series has been recognized with more than 65 awards and 175 nominations. Netflix estimates “Stranger Things” has helped create 8,000 production-related jobs in the U.S. over its five seasons and, since 2015, contributed more than $1.4 billion to U.S. GDP. In California, Netflix estimates the series contributed more than $500 million of GDP.

Netflix is doing a large marketing push with fan events in 28 cities and 21 countries as the series draws to a close. On Sunday, the streamer hosted a bike ride on a stretch of Melrose Avenue in partnership with CicLAvia where 50,000 fans were encouraged to dress in ’80s attire, or as a “Stranger Things” character. On Thursday, a “Stranger Things” float appeared in the Macy’s Thanksgiving Day parade.

The company began a phased release of the final season with four episodes that debuted Wednesday. Another three episodes will land on Christmas Day and a two-hour finale Dec. 31 on Netflix. The finale will also play in more than 350 movie theaters in the U.S. and Canada on Dec. 31 and Jan. 1.

“Stranger Things” fans Kelly Audrain and Jason Serstock said they have been rewatching the show from the beginning to refresh their memories on the whole tale, and were still on Season 2 as of earlier this month. The couple attended the premiere of the last season in Hollywood.

“The whole costuming and everything was so perfect that you just feel like you’re taken back to the ’80s,” 29-year-old Audrain said, who was dressed as “Stranger Things” character Eleven in a pink dress and sporting a mock bloody nose.

Netflix is expanding the show’s universe with the animated series “Stranger Things: Tales from ‘85” next year. In April, Netflix’s “Stranger Things: The First Shadow” stage play hit Broadway. The company has also opened “Stranger Things” pop-up stores, held live experiences and will feature immersive experiences at its Netflix House locations, including “Stranger Things: Escape the Dark” in Dallas. In Las Vegas, Netflix will offer themed foods like Surfer Boy Pizza at its Netflix Bites restaurant.

The Duffers recently told Deadline a spinoff is in the works at Netflix. Bajaria declined to share anything about that but said, “I think the world is really rich and there’s still a lot of story in there.”

But there are challenges ahead. Netflix, seen as the leader in subscription streaming, has had two major flagship series end this year — “Stranger Things” and Korean-language drama “Squid Game.” Analysts say the company will need to keep pumping out popular shows and movies to keep subscribers coming back.

Netflix has successfully expanded its “Squid Game” franchise to include reality competition series “Squid Game: The Challenge,” where more than 95% of watchers also tuned into the scripted series. Other popular franchises like Addams family series “Wednesday,” pirates tale “One Piece” and Regency-era romance “Bridgerton” are ongoing. Netflix’s hit animated movie “KPop Demon Hunters” will get a sequel.

Separately, Netflix placed a bid on parts of Warner Bros. Discovery, with interest in Warner’s Burbank studios and HBO, according to people familiar with the matter. If the acquisition is successful, it would greatly expand Netflix’s library of titles and intellectual property.

While the Duffer brothers still have projects with Netflix, they recently signed a four-year exclusive deal with Paramount for feature films, TV and streaming projects. Some industry observers viewed that as a loss for Netflix.

“The Duffers are so young, and they’re just really beginning their journey,” said Tom Nunan, a former studio and network executive. “I have no doubt they’ll be pushing out more hits and more of a variety of successes in the future,” he said, adding that the brothers’ work at Paramount could compete with Netflix.

But Bajaria noted that the Duffers still have some projects in the works at Netflix, including sci-fi series “The Boroughs” and horror series “Something Very Bad Is Going to Happen.”

“They’re always gonna be part of the Netflix family and I’m excited we still have more things with them,” Bajaria said.
