An exclusive theatrical window is one of the big reasons to go to a movie theater: you want to see a movie before it's available on streaming. Removing copyright seems like it would harm theaters pretty significantly.
The screen would become the thing. If anyone can watch anything anywhere at any time, having a 200 foot screen differentiates a theater from watching something on a phone. 99% of the time, people will choose the phone, will choose to watch sports on tv, etc. that remaining 1% might be a big enough market and without licensing fees, theaters have a lot more margin. Actually, it seems surprising they haven’t moved into…
For example the 2024 Summer Olympics, with NBC owning exclusive rights to the US market for video coverage (meaning NBC Universal, meaning Comcast) IMAX licensed the opening ceremony to be picked up from NBC and delivered to their US cinemas over IP with fixed latency. It was only the opening ceremony and no scored events. That involved NBC, IMAX, and LTN to carry the video in between. IMAX and NBC negotiated the rights and LTN got statements of agreement on that from NBC. There was involved planning and engineering work to make sure the technical part went smoothly. I'm sure the negotiations, contract writing, redlines, and final sign-off between the source and destination took longer than the tech work.
