sebuah kotak ajaib yg mngrluarkn swara yang diminati oleh seme kalangan,tada hari tanpa menonton TV, itulah gamboran masyarakat di zaman ini
menjadi penemuan fenomenal sejak dikomersialkan pada tahun 1930-an. Television telah merubah cara urang ramai mendapatkan liboran dan informasi dengan gambo bergerak yang disiarkan secara langsung. Pada awal perkembangannya, television dikembangkan oleh para jurutera eletronikyang teruja dengan penemuan telepon.

Para jurutera itu berpikir, bila swara boledikirimkan melalui kabel, gambo bergerak pun pasti bole dikirimkan dengan wayar/kabel. Perlahan-lahan, para jurutera tersebot telah mewujudkan harapan tinggi urang ramai ntok menyaksikan pengiriman gambo bergerak ...ngan tu konsep yg dinamakan teleponskop,yg merupakn gabongan telepon dan pengiriman gambo bergerak telah dptdihasilkn..
Television is a medium of communication that is widely used to transmit and receive moving images via electrical signals or electromagnetic waves which are equipped sound. The word 'television' is a combination of the words tele ('far') from the Greek and Visio ('vision') from the Latin. So television can be defined as a system of presenting the moving image and sound that can be sent from a distance.
Aircraft television available commercially in the 1920s and has become one of the main communication receiving equipment in homes, commerce and institutions, particularly as a source of entertainment and information. In 1920, television use high-powered radio transmitter to broadcast television signals to a television receiver.
Television was not invented by one person alone but through the development of cooperation of various parties over the years who contributed to make the evolution of this television. The first time television beginning in 1862 by an Italian citizen named abbel caseli who managed to find a system of sending pictures by electricity through a wire. But the basics of a new mechanical television was first invented by Paul Nipkow a student from Russia in 1884 and in 1907 on the cathode ray tube perfected by Ferdinand Braun of Strasburg University, Russia. And in 1907 professor boris Rosing managed to find the basics of electronic scanning cathode ray tube to convert vibrations into visual electronics.
Later in the year 1923-1929 John Logie Baird demonstrated the transmission of moving silhouette images first and become the world's first television broadcast. From the experiments Nipkow and Rosing munculah two types of mechanical television systems and electronic television. Then DR.zorkwin from russia perfecting a cathode ray tube called the kinescope. Kinescope tube was urgently needed for television. The tube begins to be able to transform the visual into electronic signals.
In 1927, Philo Farnsworth was the inventor of the first to transmit television images consisting of 60 horizontal lines. Farnsworth developed a dissector tube, the basis of all electronic television today. He filed the first television patent in 1927. Louis Parker finds a modern television receiver. Patents issued to Louis Parker in 1948. Marvin Middlemark create a shaped antenna "V" color TV was not a new idea, the German patent in 1904 contained the original proposal of color TV, while in 1925 a new Zworykin filed a patent disclosure for all color systems -electronic television. A successful color television system began commercial broadcasting, first authorized by the FCC on December 17, 1953 based on a system invented by RCA. And subsequently developed into television as it is now with the various forms of
