There are a number of advantages to the Direct TV offerings. Satellite Directv, for example, offers HD TV. Plus, of course, a digital video recorder service. These are not things which every cable operator offers as a matter of choice, even now.
There is also the point that the Direct TV Satellite service is, as the name implies, delivered by satellite. TYhis means that some of the packages come bundled with satellite radio stations, not just TV channels. This is of course a saving over needing another subscription and expensive box to hear those radio channels.
One or two more things about Direct TV: you get international channels from around the world but you also get full local listings. And of course there are premium movie channels and sports packages to delight the most fevered sports fan.
