Direct Broadcast satellite (DBS) delivers hundreds of TV channels to millions of people around the world. Satellite owners buy slots in space and lease assigned transponder frequencies to service providers. In this paper, I briefly introduce the history and development of DBS, the major vendors of the products, and overall market situation. In order to illustrate why DBS is such a popular technology, I also give out the comparison between DBS and the traditional cable TV. Both of them have advantages and disadvantages. But the competitive advantages of DBS will make it attract more subscribers thus gain larger market share in the future.Most network and cable programs are transmitted on a series of C-band satellites and some Ku-band satellites. These two types of satellites use different frequencies much as VHF and UHF broadcast TV use different frequencies. Communications satellites were originally designed for commercial purposes for sending telephone, radio, TV, and other signals across the country and around the world for retransmission to businesses and homes by local telephone companies, TV stations, or cable companies.

New York: John Wiley & Sons, Inc., 1993. Cable operators spent billions of dollars on preparing to offer glitzy interactive services. However, a lot has changed over the past year. The number of satellite players has shrunk from four to two: DirecTV and EchoStar. They are doing surprisingly well in rounding up new subscribers and revenue since the federal government gave them the right to retransmit local stations, which they do for an extra fee. Moreover, over the next few months, satellites will take the lead in offering interactive digital TV services, as well as two-way high-speed Internet connections, coast to coast. That has made Hughes Electronics, parent of DirecTV deals with power players including America Online, Microsoft and Blockbuster, and programmers from the National Football League to Walt Disney. They are attracted to DirecTV because its 8.7 million subscribers account for about two-thirds of the satellite market. It expects to end this year with nearly 10 million customers, up 20% over last ! Cook, William J. "1997: A New Space Odyssey." U.S. News & World Report, 3 March 1997, 44. 2.
