If you think Disney is making a mistake in ditching Netflix, think again.

When Disney announced this week that it would end its partnership with Netflix and instead launch its own Disney streaming service, shares of both companies tumbled. That’s not surprising: at first blush, this is scary news for shareholders of both. Netflix will lose extremely valuable Disney content, and Disney will take a major risk in jumping into the very-crowded streaming space on its own. (It’s easier to just sell your content to an established service than try to build a service yourself, right?)

But pundits often forget, when they talk about Disney, all of the incredibly valuable intellectual property it now owns. It is property that consumers, especially families, will pay up for.

Disney’s recent box office run is staggering. In 2016, all of the top-five highest-grossing movies globally were from Disney. Even more impressive: they were all from different Disney-owned divisions: “Captain America: Civil War” (Marvel); “Rogue One” (Lucasfilm); “Finding Dory” (Pixar); “Zootopia” (Disney Animation); and “Jungle Book” (Disney, live-action).

Disney also set a new global record for movie studios in 2016 by breaking $7 billion at the box office.

Netflix will lose those valuable movies at the end of 2018, movies like “Frozen,” “Inside Out,” “Rogue One,” and “The Avengers” franchise.

And Disney content isn’t just movies. It’s ABC, Freeform, and A&E. That’s “Quantico,” “Pretty Little Liars,” and “Duck Dynasty,” to name just one big example from each.

Netflix is going to lose all of those shows. (It gets to keep Netflix-exclusive Marvel shows, like “Daredevil” and “Luke Cage.”) As Piper Jaffray wrote in a Netflix analyst note after the announcement, “We recognize the strength of this [Disney] content, particularly for parents of younger children.”

Original content (movies and TV shows), in fact, is what Disney is known for these days. It isn’t the parks and resorts, which now make up just 20% of Disney’s profit. The media networks division, which houses ABC, ESPN, A&E, and Disney’s stakes in Hulu and Vice, contribute more than half of its profit.

Certainly Netflix has many other partners providing it with content, and many of its most-watched shows are its own original series. So there’s reason for Netflix optimism. But there’s also serious reason to expect that consumers will happily subscribe to the Disney streaming service. “Netflix doesn’t need Disney,” writes Yahoo Finance’s Justine Underhill. But the inverse is also true: Disney doesn’t need Netflix.
