Dish didn't buy blockbuster for their content, as they could have gone out and worked deals for content with the networks that they already have agreements with.
The Blockbuster name was really what Dish was after, due to the fact that it was widely recognized.
Where I believe they screwed things up is that they did not invest in an easy to use customer interface for both the streaming content and the DVD by mail service.
In my opinion the streaming service was useless to me when I had it simply because it was very difficult to find anything worth watching.
As far as the DVD service, everything I wanted to get was out of stock, and has long wait times.
Streaming is where the future is, the DVD by mail service is only good for the people who do not have a reliable Internet connection.
The way I look at it is like the VHS vs BETA days. Everything is going to VHS, and here we have Charlie trying to re-invent the Beta Max.
The only issue with the Blockbuster name is that the longer things go this way with the stores closing, and the crappy streaming service, the less people are going to see blockbuster as a name they trust.
