Within a few years, this phenomenon became widespread in other urban centers as well. By 1984, entrepreneurs in prime cities such as Mumbai and Ahmedabad had begun wiring the prominent apartment buildings to transmit several films a day. The video collection consisted mostly of film-based entertainment, both domestic and imported. Video viewing at home and in community-based video parlors increased at a fast pace. The VCR greatly multiplied entertainment options for Indian audiences, providing alternatives to Doordarshan's single-channel programming. While Doordarshan was expanding rapidly during the 1980s, the cable television industry was mushrooming in the prime cities of India. Satellite television provides a wide range of channels and services, often to areas that are not serviced by terrestrial or cable providers. Satellite television in India is delivered by the means of communications satellite and received by a satellite dish and set-top box.
