I'm guessing Dish bought Blockbuster for name more than anything else. From news Routers, it seem Dish Network is trying to get into wireless network system as earlier this year it bought DBSD, which is one of three "mobile satellite services" companies that own rights to valuable broadcast spectrum.

They also bought Hughes Communications back in February which is provider of broadband satellite network products. Together, the deals could give Dish the tools it needs to deliver movies to phones and iPads. And use Blockbuster as virtual store front for the delivery of those contents.

Your guess is good as mine as what are they planning to do with physical stores
