But like Disney, the companies that own Netflix shows are bound by deals they made a long time ago, said the people, who asked not to be identified discussing non-public information.
Of the 10 most popular licensed programmes on Netflix, at least eight will be on Netflix for years to come, according to the people. Grey's Anatomy, The Walking Dead and a slate of shows from the CW network, including Riverdale and Supernatural, will stay on Netflix for as long as they remain on the air — and then for three to six years after that, said the people. That means they will be on Netflix until at least 2023, and likely well past that.
And when the big Marvel, Star Wars and Pixar films return to Netflix in a few years, they'll disappear from Disney's own online service, according to the people.
Disney began licensing movies to Netflix in 2012, four years after the streaming service gained access to 2500 movies through an arrangement with the Starz cable network. Hollywood studios saw Netflix as a lucrative way to replace shrinking DVD sales. Nickelodeon, Warner Bros, Fox and others all cashed in, handing Netflix some of their most popular programmes. Many doubted the long-term viability of Netflix, so the agreements may not have seemed like much of a gamble.
But their shows were a boon for Netflix's nascent streaming service, which had a small library of old movies when it debuted in 2007. Reruns of popular hits are a perennial draw and the foundation of the lineup at TV networks like TBS and Comedy Central. Netflix operated online for five years before releasing its first original series, building its audience online with shows owned by other companies. Thousands of them.
Netflix's library of other companies' shows was so exhaustive that, ahead of the company's 2013 debut in the UK, Kasey Moore started a website just to track what shows were coming onto and being taken off the service every month. Moore called the website What's on Netflix, and it now gets 4.5 million visitors a month.
"You've got thousands of titles in the Netflix library," Moore said in an interview. "It just made sense for someone to track it all."
As early as 2011, studios started to worry that Netflix was damaging their businesses. The company surpassed 20 million customers online, and TV viewership among young viewers was in decline. But they couldn't turn down the money. Disney was expected to bank more than US$350 million a year by licensing Netflix the rights to offer its movies after they left theatres, according to analysts' estimates at the time.
Those concerns have intensified as traditional TV viewing sputters and Netflix continues to grow. And now the world's largest media companies are rushing to build their own online services. Disney will unveil Disney+ in November, followed by offerings from AT&T and NBCUniversal. All of them are assessing which shows they will need to lure subscribers.
"We are going to have to take a lot of the great content we own that's been licensed elsewhere and bring that back into the fold," AT&T Chief Executive Officer Randall Stephenson said at a May investor conference.
Just one problem: AT&T, which bought Time Warner for US$85 billion last year, has a lot of its film and TV content tied up with Netflix and others. Warner Bros, which owns Friends, is the biggest TV producer in Hollywood and has built its business licensing shows to third parties.
Under AT&T, it will reserve some for a new streaming service, but will continue to sell programmes to Netflix, Amazon.com Inc. and Disney's Hulu, according to several people familiar with its plans. The home of Friends and The Big Bang Theory counts too much on such sales to forgo third-party deals.
NBCUniversal is thinking similarly. The company could keep The Office for its upcoming streaming service, but has held talks with Netflix, Hulu, Amazon and AT&T about selling the rights. Even if NBCUniversal decides to keep the show for itself, it will still be licensing shows such as The Good Place to Netflix.
Just the same, Netflix has been producing more on its own. The company will have 1000-plus pieces of original programming this year. By the time The Office deal ends, Netflix will have at least 3000 new programmes in its library and likely surpass 200 million subscribers worldwide.
"People are missing it," said Nathanson. "The loss of back titles will not kill Netflix or slow subscriber growth. It just forces them to make more original content."
