I was going to quote posts but there is too much information and I'm lazy today....
I don't see any other argument but that delivery of Satellite services is tremendously more expensive than streaming it. In just about every way, equipment, truck rolls (If they need to send someone to help set up streaming it would be a fraction of the cost - in fact they may indeed hire the teenager next door lol) expectation of needing to replace satellites, and more.
So with that in mind, even if At&t has to take a loss as I believe they would in shedding Directv some of that loss is offset in what they won't have to spend going forward. In the fourth quarter earnings call last year At&t said "We have a customer base left on the streaming that's growing, and is a highly engaged.... We like where we are in how we're positioning the streaming product," Not sure I see anything even approaching that type of glowing remarks about Satellite service.
And in November the CEO said we have launched our last satellite. And finally the theme they were portraying was their focus on lessening debt. Sounds like the shedding of Directv if possible to me.
The more I give it thought the more I see a path for the two satellite companies to merge. Directv/customer base is worth more to DISH than any other media company. If satellite is less appealing now than in the past what makes us think another media company will bail out At&t and take on that service? Sure there will be tire kicking but I bet advisers within the companies will advise it isn't a good risk.
If DISH could negotiate programming contracts with around 25+ Million they have a far better chance of staying around for awhile. They still have to find a way to expand into other areas but it gives them more time while serving a part of the population who does not want streaming, can't stream, does not want cable for various reasons, want more reliability and capability of signal with power loses etc.
None of that means it is an easy path even if DISH acquires/merges. They still have to distinguish themselves from Cable, they have to find a way to be consistently less expensive which generally they are, and find other ways to stand out as a better alternative.
The FCC is a different issue. I believe they will approve a merger of some type, BUT - I also think they have to believe both services will not be able to survive without it just as they did with Satellite radio.
