From what I have been told by various people the 5 that were kept were based on the number of people watching those channels.
Dish has software ini the boxes that keeps track of what folks are watching.
Okay Scott, maybe most watched, but to Me that does not necessarily mean best. Best can mean very different things to many different people. Some people would not know best if it were staring them in the face. I cannot exactly remember the exact five that were still there after they removed most I remember Monsters, Rush, Kung Fu, and I am not sure what the other two were because I was in such shock at the removals of the ones I liked, but I can think of at least 5 other Voom channels I would keep. The ones they kept were not them. There are always differences of opinions. I think the removal of Voom was all about money with no concern for the viewers.
