None of such deals have materialized yet, of course, and also it needs to be pointed out that several movie companies have discarded these ideas before because they know that by offering you new titles so early they are going to lose on all the overpriced cold drinks, and snacks they sell you at the theatre. There's also piracy concerns. If a movie is available early, regardless of the DRM tech these companies deploy, good-enough footage of the movies will crop up on file-sharing websites almost immediately.
But leaving all those aspects aside, would you be interested in getting new titles just hours or a week or two after they hit the cinemas? Would you want to end the decades-long practice of going to a theater?
