Associating the DirecTV brand with Dish would only drag DirecTV down. Better to wipe them out, settle the various lawsuits Charlie has invited, and keep what is worth keeping. Chop shop.
FCC will never go for that. Dish is not a failing company in financial struggle that can be bought out and chopped up, it is a company that is doing very well financially, and has 14 million customers. They will do perfectly fine on their own, and besides the FCC not approving such a scenario, I think Dish would rather continue on their own than have it being chopped up.
If they ever merge, it will probably an actual merger with a name change. Just like SiriusXM, they would become something like DirecDish or something similar.
Personally, I don't think a merger will happen any time soon. And if they do, they will probably remain two separate companies for many years, while from the top level down they will slowly - say over 10 years - work towards a compatible standard in technology so they can become one company.
Look at cable acquisitions for instance: In 2008, when Adelphia failed, TWC and Comcast bought up the pieces and started dividing up their markets. TWC got all of Los Angeles, and gained all of Adelphia and Comcast in this market, where they gave up other markets to Comcast. That was 2008.
Four years later, my mother-in-law still has a Adelphia DVR, people still have Comcast equipment, and they essentially are STILL running 3 networks with 3 different setups. They even haven't streamlined the channel lineups yet. TWC in my home town has a vastly different channel lineup and channel location as the town my mother-in-law lives in, only 5 minutes down the road.
Dish may be the smaller party in a potential merger, but they would not be absorbed. It is much more likely that IF a merger would take place, they will stay separate companies for at least 5 years with a corporate merger, and then slowly merge into a one-name company that might not carry either name at all. They would have to come up with a technology merging plan first.
