Not talking about the Apps. Talking about the On Demand on the television set through cable that you access through your remote control. 

On Demand is all but dead. Blame the content owners for making a conscious decision to move their content to apps.

I'm guessing part of the reason is because it's easier for them to put everything all in one place, considering people don't necessarily watch on a TV these days AND so that subscribers to different providers (Hulu, Amazon, U-Verse, Xfinity, and directly) all get the same content.

Networks like HBO, Showtime & Starz are moving 90% of their On Demand content to their own streaming services like HBOMax and Showtime Anytime.  Same with A&E, Bravo, Comedy Central, etc.

HBO and Starz still have hundreds of choices. Showtime and TMC are the one missing most of the content. It may have something to do with ATT trying to get people off of UVerse. I love UVerse and so do everyone that has it. 

AT&T doesn't control what each channel gives them.

As already said, Showtime has an app. It wouldn't make sense that AT&T is denying people content when that content (plus more) is available elsewhere. That would seem like a fail on AT&T's part.

Can I use my ATT UVerse account to login to the Showtime Streaming App (not Showtime Anytime it's going away)

It won't work with Paramount+, as that's a separate thing.

Download the Showtime app and see what happens. Are you subscribed to Showtime via U-Verse?

It sounds like both Showtime streaming options will only be an available through Paramount+.

Yeah, I can understand that. Showtime by itself was(?) probably a very similar price to the Paramount+ price that includes Showtime.

Why have two apps when you can have one that includes more stuff than just the old app?

I have Showtime (U450) and I have Paramount+ but it is kind of messed up if you can’t access any Showtime OD content without paying for Paramount+.

I see a VERY LIMITED amount of stuff on my Showtime on Demand menu.

And yeah, it's obvious the channel owners want to move people to the apps. At one time, HBO on Demand had a lot of stuff. Now? Not so.

MGM+ has over 300 titles. Oddly enough, Epix has a fraction of that...and didn't Epix rebrand to MGM+?

I have the UVerse 450 package but when I download the Showtime App (not Showtime Anytime) it asks for a UID and Password.  It never asks if I have a media provider.  It just asks for my UID and Password.  I enter the ATT UVerse authentication, and it says not a good authentication.  It appears that when Showtime Anytime goes away ATT UVerse customers will no longer be able to Stream Showtime programming and the only Showtime that will be available is through On Demand which is very minimal programming.

You are correct.  Showtime App is a separate PAID service.  Showtime Anytime is the service that is attached to your U-verse acct.

It may be time to abandon UVerse.  I'm paying a premium price and not getting Premium services.  I've also noticed issues with local TV channels having contract disputes with ATT.  First it was local Fox out of service for over a month and now NBC not available here in St. Louis.
