The way movies have been released have changed over the past few years. Back in the day, movies came out only in theaters, then would be released on video or DVD after their theatrical run. That later shifted to movies also being released on demand or for rent online after they left theaters.
But, in recent years, some movies have been coming out on streaming services at the same time as their theatrical releases, or not coming out in theaters at all and JUST being released online in places like Netflix or HBO Max. Disney has definitely taken part in this new practice, and it has caused some controversy. But soon, they might not have to choose between the two.
