So what is the speculation on why Dish didn't add the Full suite of HBO/Max channels that it had before they were pulled in 2018? A lot of people in rural areas do not have sufficient internet speeds and streaming and On demand are not an option. My speculation is Bandwidth..or HBO/Max are going to significantly downsize the channels they broadcast. Just my 2 cents.
It's interesting to note that on AT&T's own streaming cable TV service, AT&T TV, they've only ever included a few of the linear HBO channels, despite the fact that they own HBO! That service only carries HBO, HBO 2, HBO Family and HBO Latino. And it didn't even originally have HBO 2. But then if you have AT&T TV, you necessarily have home internet service, so you can stream the full HBO catalog via AT&T TV's on-demand platform and also via the separate HBO Max app. All the HBO content is always ad-free and uncut, regardless of how you watch.
But it's not just HBO. AT&T TV does the same with the other premium services. For instance, the only carry Showtime, Showtime 2 and Showtime Extreme. And just Cinemax and ActionMax for that service.
It's also interesting that AT&T TV's cloud DVR doesn't allow you to record from any of the premium linear channels; you can only bookmark the on-demand version for later viewing. But really, when all the content is available on-demand and ad-free, what's the point of recording from the linear channels? HD PQ is actually usually better in on-demand streaming content than on linear channels anyhow.
The need for the linear channels themselves is even questionable. It's clear that HBO's long-term plan is to morph into something more like Netflix via their HBO Max app. I doubt that the original HBO linear channel ever goes away (especially as long as it continues to air the occasional live show/event) but I can see them de-emphasizing them and killing some of them off. First to go would probably be HBO Zone, HBO Comedy, and HBO Signature -- all three are missing on AT&T TV and at least two of those didn't return to DISH (not sure about Signature). IMO, the linear channels simply serve as a way for the service to advertise its content with easy viewer sampling. Sure, you might stumble into a show or movie mid-way through and stick with it but many would just opt to watch it from the start on-demand, or set it up to record the next time it comes on.
Companies prefer it when you view their content via their own app, where they control the UI and they can glean valuable user data. (And in the case of the cheaper HBO Max plan, they can serve up lucrative targeted ads in the non-HBO content.) Note how HBO has removed their content from other streaming apps/UIs. It's no longer available as an add-on in The Roku Channel or the Apple TV app and will be gone later this year from Amazon's Prime Video app. Those moves drive cord-cutters toward the HBO Max app.
Perhaps in the next few years, we'll see HBO restructure their agreements with cable TV operators like Comcast, Charter, Verizon, etc. so that they no longer offer their content via those operators' native on-demand platforms, only via the HBO Max app which they push to be included on those cable boxes. (It's already on Comcast's boxes.) And perhaps they kill off a few of the lesser HBO linear channels and require that the surviving ones be non-recordable. Clicking to record a show on HBO might add a bookmark to your cable DVR library that, when clicked, just takes you to that show inside the HBO Max app. Lastly, perhaps we see those HBO linear channels also available to stream inside the HBO Max app, giving users even more reason to stay there versus exiting to other UIs.
All speculation, of course. And I wouldn't expect such changes to happen on Dish or DirecTV, since many satellite TV users don't have broadband. I expect such folks will constitute an increasing share of satellite TV users in the coming years as the overall subscription levels continue to erode due to all the (often cheaper) video options available for those with broadband.
