History of Televison
The television and the content that it brings us continue to be two of the most impactful inventions that we have in our homes. There will always be debates on how much TV to watch, what content to watch and whether it enriches our lives or dumbs us down. However there is absolutely no doubt that without the TV the world would have been a very, very different place.
Most homes in the developed world consist of more than two TVâs per home and many houses in the third world usually own one TV per home. If thatâs not the case then there are often âcommunityâ TVâs where people in villages come to wind down with after a long day of work. Some other interesting facts and figures on TVâs are:
Neilsen Media Research completed a survey which revealed that an average American home watches 8 hours of TV every day.
Televisions may contain hazardous material, specifically lead which can leak into landfills and contaminate the soil.
These days kids under 6 years old spend as much time â" if not more - watching TV as they do playing outside.

Important Inventors in the World of TVâs
There were two schools of thought when it came to inventors for the television:
- Those who followed Paul Nipkowâs rotating discs
- Those who followed A.A. Campbell-Swinton and Boris Rosingâs cathode ray tubes to develop an electronic television
After some experimentation it seemed that the electronic based TVâs were superior to those of the rotating disc and became the single path on which all TVâs emerged from. Other important inventors in the history of television include:
John Logi Baird â" Patented a technology which allowed images to be reflected light rather than silhouettes.
Charles Francis Jenkins: Invented the radiovision, a mechanical television system.
Vladamir Kosma Zworykin, Karl Braun â" Both worked on various versions of the cathode ray tube oscilloscope (CRT) on which the picture tube in modern TV sets is based on.
Philo T. Farnsworth â" Invented the dissector tube which is an important component of all current electronic televisions.
Louis Parker â" Invented the modern changeable television receiver.
Marvin Middlemark â" Invented the âVâ shaped âRabbit Earâ antennas.

Digital Light Processing (DLP) â" Rather than rely on the cathode ray tube, DLP TVâs function due to a Digital Micromirror Device, a type of optical semiconductor.
Liquid Crystal Display (LCD) â" There are many different types of LCD TVâs now available in the market and are quickly becoming the most popular choice for consumers.
