television. The Columbia Encyclopedia, Sixth Edition. 2001-05 Television has become a major industry, especially in the industrialized nations, and a major medium of communication and source of home entertainment. Television is put to varied use in industry, e.g., for surveillance in places inaccessible to or dangerous for human beings; in science, e.g., in tissue microscopy (see microscope); and in education. When a television program is broadcast, the varying electrical signals are then amplified and used to modulate a carrier wave (see modulation); the modulated carrier is usually fed to an antenna, where it is converted to electromagnetic waves and broadcast over a large region. www.bartleby.com /65/te/televis.html   (2128 words)

Television In the television receiver, another electron beam–or set of electron beams, in the case of color television–uses the signals recorded by the camera to reproduce the original image on the receiver's screen.

Later, however, the growth of color television was delayed because it had to be compatible with monochrome–that is, color television would have to use the same channels as monochrome television and be receivable in fl and white on monochrome sets. autocww.colorado.edu /~blackmon/E64ContentFiles/CommunicationsTechnologies/Television.html   (5408 words)
