The service will cost $14.99 per month for new customers, though current HBO Now customers are speculated to be automatically upgraded to HBO Max without any extra fees if they are billed through the App Store or subscribe via Apple TV Channels.
HBO is currently preparing to launch HBO Max, a video streaming service that will open on May 27 with 10,000 hours of content.
The late-April delay enabled users to continue using HBO Now on the Apple TV until May 15, but now access has been pulled on the second- and third-generation Apple TV.
The original decision to pull the HBO Go and HBO Now apps from earlier Apple TV models in April was postponed by a month.
Following a one-month extension, HBO Now is no longer available to use on the second-generation and third-generation Apple TV, leaving users with the prospect of upgrading to a newer model or performing a workaround to continue accessing the service.
