So what about existing HBO subscribers? Here's what we know so far.
HBO Now subscribers get upgraded to Max for free
is HBO's standalone streaming service, which currently costs the same as HBO Max: $14.99 a month. In May, people who currently subscribe to HBO Now can switch to HBO Max to unlock Max's much bigger catalog for the same price. Nine million people currently pay for HBO Now.
According to HBO Max's FAQ, however, there's a catch. Only new and existing HBO Now subscribers who subscribe through hbonow.com and are billed by HBO are eligible for the free upgrade. The offer is "not currently available to HBO subscribers that obtain their subscriptions through third-party providers that are authorized to distribute the HBO Now service," for example Roku or Apple. The FAQ says users subscribed to those third-party providers should "stay tuned for more details" as the launch date approaches.
HBO subscribers via AT&T get Max for free
If you pay for the traditional HBO premium network via a pay TV package through AT&T, then. AT&T owns satellite broadcaster DirecTV, IPTV service U-verse, service and , and says 10 million current TV HBO subscribers will get Max for free. That also includes AT&T wireless users who can add HBO with certain unlimited plans.
Other HBO subscribers and HBO Go? We'll see
If you don't subscribe to HBO Now or an AT&T-owned provider, the situation is less clear.
AT&T is still in talks with other pay TV providers about offering HBO Max to their traditional HBO subscribers. That means subscribers who get HBO from linear providers such as Comcast, Spectrum, Dish Network, as well as streamers like, , and , will have to wait to see whether they too can get Max for free.
AT&T did say that during the transition to HBO Max, existing HBO-branded services will continue to be offered via cable and other traditional outlets. Those services include, the app that currently allows existing HBO subscribers to stream HBO programming. In other words, AT&T isn't forcing customers to migrate to HBO Max, although eventually it expects them to do so naturally.
