“Dumbo,” the live-action and CGI remake of a 1941 Disney classic, is currently in theaters. Last week, Disney unveiled its new streaming service, Disney+.

BURBANK, Calif. — For nearly two years, the entertainment industry has talked about, fretted over, lamented and lauded the streaming efforts of Disney, one of the country’s most established legacy content firms.

Last week, it finally offered a glimpse into what all the murmuring was about.

“A core tenet since Walt Disney founded the company is to create change and not just sit back and watch it happen,” Disney Chief Executive Officer Robert Iger said, addressing a so-called “Investor Day” on the studio’s lot. “Borrowing from one of Walt’s greatest strengths takes courage,” he added, noting that the service, called Disney+, will demonstrate a lot of that.

The service will be launched Nov. 12, and will cost $6.99 a month — or $69.99 annually (which works out to about $5.83 a month).

It’s easy to understand why interest in Disney’s streaming service has swirled since the mid-2017 announcement. Disney is one of the most dominant entertainment firms of our time, producing and releasing blue-chip content from Marvel to Pixar to Lucasfilm. And after watching Netflix build an empire in part on the back of Disney’s own library, it’s striking back.

A legacy company has not taken on a world that has been dominated by Silicon Valley, not like this.

There’s Hulu, aggregating the content of the biggest content providers (including Disney) with a sprinkling of new shows. (The service was part of Disney’s investor-day promotion.) And there’s CBS All Access, which has gone for a piece of the streaming business with its own shows.

But a single company bringing everything in-house and soliciting consumers the way Disney is remains new.

The service will focus on high-end brands such as “Star Wars” and “Toy Story” more than on Netflix’s volume business. Disney+ will be, for instance, the home for all theatrical movies released by Disney. It will also eventually be the home for its classic film library (still living in other places under current deals).

The company on Thursday offered some more details on how it would carry out its plans.

The company said that Roku and Playstation are the platforms where Disney+ will certainly be available, with “a full array of platforms in place” come launch.

It also showed off the interface, which appears pretty straightforward — five tiles for its five content pillars on its home screen. Users are able to click on one of them and then a few of the new and original titles. That marks a contrast to Netflix and other services which rely on a much larger mix of titles and search functions and algorithms to find them.

Disney+ will launch with plenty of originals: 25 new episodic series and 10 movies in year one. By year five the former will go to 50 but the movie number will remain constant, executives said.

The presentation saw Disney executives offering details on what will be available on the service.

Lucasfilm chief Kathleen Kennedy, for instance, said that “the first two trilogies plus Force Awakens and Rogue One” will be available on day one of Disney+ with “remaining titles to come within the first year, including “Star Wars: Episode IX.”

Marvel head Kevin Feige, meanwhile, unveiled details of a “What If” series that will ask questions such as, “What if Peggy Carter took the serum instead of Steve Rogers?” Captain Marvel will be available on “Day One” of Disney+, along with Iron Man and other golden oldies, Feige said.

Disney+ chief Kevin Mayer said that “all content will be downloadable and accessible offline on an unlimited basis” as long as people remain subscribers.

And Disney+ will be The Simpsons’ streaming home, with all 30 seasons available at launch.

Disney CFO Christine McCarthy said that Disney+ will probably lose money between now and 2023, “peaking” between 2020 and 2022. Profitability can be expected in 2024, she said.

Despite those losses, the company is betting that the cost, and the popularity of its offerings, will induce a high number of subscriptions.

There will be no free ad-centric option, Mayer said. “For Disney, these brands at this time, no ads is the right call,” he said.
