HBO Max currently makes $600 million a month in sub revenue, or $7.2 billion a year. Thats at 40m subs, they have a goal of 150m subs in the next 4 years which would pull down $2 billion a month or $24 billion a year. Netflix and Disney make even more money from streaming, but HBO Max isn't even available in most countries yet. You are not dependent on hits either, as long as you release enough mediocre shit to keep people subbed you make money, and you keep 90% of the money vs less than 40% with theater box office.
Theater revenue is absolute chump change compared to these numbers and the goal always will be to drive sub revenue, its what Netflix and Disney are all about and Apple, Universal, Amazon, Warner Bros wants their part of the pie. Whatever they are saying in public is all a lie to not get theaters to shut them out, the eventual goal is to release everything on streamer services as exclusives and any theater revenue is just a nice bonus but not really part of any plan.
