The word television was coined by a Russian scientist Constantin Perskyi in a paper he presented at the International Electricity Congress at the International World Fair in Paris on August 25, 1900. Even before that, Paul Gottlieb Nipkow, a German student, had patented the first television in 1884. It was a electromechanical device based on the photoconductivity of the element Selenium and Nipkow’s spinning disk with a series of holes of equal diameter drilled into it at equal distances. In the camera unit, as the disk spun in front of the object, each hole produced a scan line which was captured by a light detecting device behind it. The scan line was transmitted by radio wave to the reproducer or receiving unit. This basic television and other refinements that came after it were however restricted to transmission of still images and silhouettes. It was only on October 2, 1925 that the Scottish scientist John Logie Baird, who took the lead in development of the electromechanical television, achieved live transmission of moving half-tone images in his laboratory. Baird’s endeavour took the electromechanical television through a continuous phase of technical development ranging from the first transatlantic transmission between London and New York by his company in 1928, the first transmission between shore to ship, demonstratin of the first electromechanical colour, infrared and stereoscopic television to the first live transmission, of the Epson Derby in 1931 and demonstration of the ultra short-wave television in 1932.

The objective of the project is to highlight the impact of a selected substance on the environment. In this regard, the paper specifically examines health effects of mercury from dietary fish. The paper narrows down to two regions; the U.S.A (New Hampshire) and Bangladesh.
However, it is quite evident that a greater percentage of the Australian population does not know how the images come about in the television despite their knowledge on how to use the remote controls. The transmission process of a TV and that of a radio are the similar in that radio uses radio waves to transmit sound just like a television (Arrow, 2009:89).

One of the people who had contributed much to the development of television is Delbert Mann, the man behind such works as the television series Lights Out (1949), The Philco-Goodyear Television Playhouse (1949-1955), and the TV drama Marty, which was later translated to the wide screen in 1954 and won an Academy Award for Best Picture, Best Director, and Best Leading Actor.
Quite simply it is impossible to imagine the latter half of the 20th century without the powerful images delivered by television. From the fantastic images of men walking on the moon to the horrific images of planes flying in the World Trade Center, television more than any other medium is responsible for the shaping of the consciousness of modern man.
Radio is the wireless transmission of signals by modulation of electromagnetic waves that have frequencies below those of light (Wikipedia). Radio waves are created whenever a charged object accelerates with a frequency that falls within the radio frequency. In radio this acceleration is caused by an alternating current in an antenna.
This creates a need in the child to watch television instead of interacting with adults. Especially when the child is left alone in front of the television from long periods of time, their language can be developmentally delayed. The
This paper outlines several sub topics that are pertinent to design principles intended for interactive programming of television.
Interactive television (iTV) also referred to as enhanced television (eTV), is television or video programming incorporating enhanced substance
