In every one of your posts on this topic, your logic is flawed. In this case, there would be no more calls than usual, or a very minimal increase. It can be done online. (Unless you have Dish, where you can only add, and they make you call to downgrade AND charge you $5. So, it's their fault you have to call.)
Mini-packs are the best thing that could happen to cable and dbs for the consumer. Yes, the per-channel cost would be higher than now. But, the total subscription cost would go down for many, stay the same for many, and go up for only a few.
Will it be a little more difficult for the providers? Possibly. I don't care. That's their job, to provide what the consumers want, not what they want the consumers to have.
News Pack (CNN, HNN, FNC, MSNBC, CNBC, etc)
Knowledge Pack (TLC, Disc, NGC, Sci, Military, Animal, etc)
Lifestyle Pack (Food, DIY, HGTV, Lime, etc)
Entertainment Pack (probably have multiple tiers due to number of channels in this category)
Movie Pack (non-premium)
Kids Pack (Nick, Diz, Cartoon, Sprout, etc)
Sports Pack (Maybe have multiple tiers)
Locals Pack (local OTA plus RSNs)
HD Pack (as they do now)
Porn Pack (as they do now)
Various Int'l Packs (as they have now)
Various Premium Packs (as they do now)
Piece of cake, technically. Consumers would love it. Providers would hate it.
