The television industry is comprised of establishments primarily concerned with the television as an electronic and technological device, and with the transmitting and receiving of signals through the use of a television set. Televisions are devices used for telecommunication, and the images they project have been black and white, monochromatic, or multicolored throughout history. The images displayed on a television are typically accompanied by audio.
In modern times, innovations in television have led to flat-screen panels, high-definition TV, three-dimensional capabilities for television, and the emerging technology of interactive television. Televisions, and a variety of television subscriptions and programming, have become common in the home and in places of work. They are used not only for leisure time, but also for marketing strategies and information (such as news reports, weather, etc.).
Competition exists in this industry between television manufacturers, wholesalers, and retailers, and also between television programming companies. Demand in the television industry is dependent upon the continuation of new technological innovations, the necessity to upgrade or replace televisions, and (in the home) the personal income of the consumer. Larger corporations have advantages due to economies of scale in financial arenas as well as marketing. Small companies strive to provide excellent customer service and to offer televisions or related services that cater to the needs and wants of consumers. Individual companies prioritize the effective nature of their marketing strategies.
