HBO Max was renamed Max, and Warner Bros. Discovery lost subscribers::Warner Bros. Discovery lost 1.8 million subscribers in the second quarter of 2023 following HBO Max’s rebrand to Max. The company now has 95.8 million subscribers across all of its services.
HBO was known for low volume but high quality content. I think Apple is trying to copy them (at exceedingly low volumes), but there is really no other service in that space.
Disney+ is similar. Obviously they have the massive library of movies, but their TV shows have been fairly similar to Apple TV.
