Over the years the HBO Zone has been briefly discussed on at least 4 different Charlie Chats, most recently a little over a year ago, that I can remember, starting several years ago. In one chat, one of the honored gusts was a muckie-muck from HBO, and a caller asked about getting HBO the Zone (I think the same guy called a year later), and Charlie took advantage of the situation and said, "The reason we don't have HBO The Zone is because HBO wants too much money!" A quick camera cut to the the female HBO exec as she sheepishly grinned and the peanut gallery and all in studio laughed. It really was one of those Charlie Ergan comical moments.
In subsequent chats he continued to mention price as the primary reason, but later changed the reason by having the previous programming exec say that the same content on HBO The Zone could be seen on the other HBO's they offered. This was generally true in the past as all these "theme" premium movie channels, in fact, do play virtually the same content as seen on the flagship channels. It really is marketing and BS just to create the multi-plex model that is really designed to force cable and sat to pay for these channels and charge us more money.
The flagship channels show a variety of movies and TV shows for which they have the rights to air. Now, take that same content from the flagship channels and break it up according to theme such as Comedy, Women's, Family, whatever, and air those themed movies on the themed channel, and you don't have to pay rights for additional content to fill up these themed channel. The irony is that the most unique films on the themed channels are often low-budget, low-brow, overall poor quality (as in script, writing, ideas) movies. Kind of the same junk available on DishONLINE.
However, there are a few channels that truly come closer to airing good quality, unique content such as Starz Cinema (although there is still a fair amount of overlap) or HBO Comedy airing all those old comics stand up performances. But, in general, it really is a scam. However, one good thing about the scam is that it does offer more opportunities to catch a movie one may have missed, and it does provide the same content spread over many show times as opposed to one channel.
