NEW YORK — As Disney debuts its Disney Plus streaming service with an arsenal of marquee franchises including Marvel and Star Wars, the $7-a-month commercial-free service is poised to set the standard for other services like WarnerMedia’s HBO Max and NBCUniversal’s Peacock to follow.

Besides classic characters such as Snow White and Pinocchio, Disney has Pixar, Marvel, Star Wars and National Geographic — big names that most people would recognize. Disney Plus will also have all 30 past seasons of “The Simpsons.” Original shows include “The Mandalorian,” set in the Star Wars universe, and one on the Marvel character Loki.

Melissa Knerr, 26, a criminal defense attorney in Springfield, Mo., already has Hulu, Netflix and Amazon Prime and wasn’t sure she wanted to pay for another one. She said she was swayed by Disney Plus’s price tag and its “sheer amount of content.”

“I really love both the Star Wars and Marvel franchises and I grew up watching classic Disney shows and movies so I do think there will be enough content for me,” she said.

Disney Plus’s $7 a month price is about half of the $13 streaming giant Netflix charges for its most popular plan, and there are discounts for paying for a full year up front. Disney is also offering a $13 package bundling Disney Plus with two other services it owns, Hulu and ESPN Plus. That’s $5 cheaper than signing up for each one individually.

Everything won’t be available to stream right away, though, as Disney needs to wait for existing deals with rival services to expire. Recent movies missing at launch include the animated Pixar movie “Coco” and the live-action “Beauty and the Beast.” Disney expects 620 movies and 10,000 TV episodes by 2024, up from 500 movies and 7,500 episodes at release Tuesday.
