TV via satellite from AT&T

AT&T's Satellite Television Service, which relays TV feeds by means of the Comstar domestic communications satellite system, is discussed. Advantages include the ability to provide multiple feeds of program and advertising material simultaneously to affiliates, which can help accommodate the trend toward greater program diversity, and the ability to distribute one signal to many points, making their use economically attractive. A proposed radio service from AT&T is also discussed, which could provide radio broadcasters and programmers with a high-quality, versatile means of transmitting radio programs via satellite.
