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.

In 1997, India, which also feared excessive western influences on its population of almost 1 billion, banned direct-to-home satellite television broadcast services. Amid a furor, which included a lawsuit by News Corp., it declared that the ban would only be temporary, until the government could set up a broadcast authority. A bill to establish the regulatory agency has since been introduced in India's Parliament. DBS companies venture into new business areas, America Online partnered with DirecTV, Hughes Network Systems, Philips Electronics, and Network Computer to work on developing "AOL TV." DirecTV and AOL planned to work together on a service that would combine digital satellite television programming and AOL TV's enhanced interactive TV Internet service. Hughes Network Services planned to design and build a dual-purpose set-top receiver, complete with an advanced set-top box for AOL TV provided by Philips. Network Computer's contribution was to provide a complete software platform for the new service through the company's TV Navigator software. Brad Beale, DirecTV's vice president of advanced products, says interactive services fit his company's strategic aims: "With the introduction of our interactive services, we're taking television entertainment to the next level by bringing varying levels of interactivity to a consumer's television viewing experience." Multi TV watch Need additional receivers$90/each Need additional receivers As of 1999, there were more than 10 million DBS subscribers in the United States, up from 8 million in 1998 and 6 million in 1997. Thousands of viewers sign on every day, and industry analysts predict more than 12 million by the year 2000. However, all the current providers are in heavy debt and operating at a loss. The providers 'policy of subsidizing the cost of the customers' receiving equipment down to exacerbates the operating losses as low as $100 in order to attract market share. Since none of the receiving systems is compatible, if a provider goes out of business, as AlphaStar has already, customers are left with worthless equipment. DBS firms are seeking to expand the business by serving new categories of customers.
