One of the best inventions in the world of digital media, television is a telecommunicating system that transmits images, accompanied with sounds and special effects, over a long distance. The word television is derived from two words – tele (which means “far” in Greek) and visio (which means “vision” or “sight” in Latin).
Paul Gottlieb Nipkow, a German student, proposed the first electromechanical television system in 1885. The discovery of cathode ray tubes in 1897, by K. F. Braun was a major landmark. Later in 1927, Philo Taylor Farnsworth envisioned the first fully electronic system. He conducted the world’s premier public demonstration of an all-electronic television system on August 25, 1934, at the Franklin Institute in Philadelphia.
Besides Farnsworth, Vladimir Kosma Zworykin is also sometimes called the Father of the television because of his invention of iconoscope in 1923 and kinescope in 1929. On July 3, 1928, John Logie Baird demonstrated the world’s first color transmission, which was a turning point in the history of televisions. Meanwhile, the Americans began their first full scheduled television service.
The first color television system approved by the Federal Communications Commission (FCC) employed a motor-driven disk in three primary colors, developed by the Columbia Broadcasting System (CBS). In 1950, the FCC declared it as the standard one for the U.S. At the same time, Radio Corporation of America (RCA) developed a similar compatible system, which later became more popular than the CBS system.
Standard definition TV (SDTV) and high definition TV (HDTV) are the two categories of display formats for digital television (DTV) transmissions, which are known for their higher-quality viewing experience.
Televisions are at present the prime source of entertainment and education. They are a fertile ground for advertising, as they are the easiest tools to reach out to the public. Plasma Televisions, LCD Televisions, and Flat Screen Televisions feature as the prominent kinds.
