Dish and DirecTV use the same head-end measurement for their channels. It's a WASTE of bandwidth as there are over 1000 Dish and DirecTV channels showing effectively the same programming - the viewer is ocked out of receiving 200 copies of ABC, CBS, NBC, FOX and others - but the channels are still in use.

Not true---Dish and Direct use "spot beams" to transmit their local channel service. This means, for example, that Greensboro local channels are transmitted from the satelite to an area only a couple hundred miles in radius around Greensboro. That way, the same bandwidth can be used to transmit locals in other areas of the country. Even so, providing bandwidth for full powered stations has been a problem. There are still a number of smaller markets where local channels are still not available on one or both satelite services---for example Wilmington still does not have locals on Dish---Bluefield WV lacks local service from either. Now, both sat companies have moved on and are trying to provide HD locals for as many major markets as possible---the big 4 are available on both sat services in Charlotte and Raleigh/Durham.
