Many would argue that HBO Max will be the winner in the streaming movie battle. HBO is THE Home Box Office. Subscribers of HBO have been trained to tune in to the network for movies. While Game of Thrones and The Sopranos made Sunday Night the night to watch TV shows on HBO, it is still the case that most people think of movies when they open the HBO streaming app or turn on the HBO channel. They are also spending billions on airing movies on release dates on HBO Max.
