Who Invented The First Television

Who invented the first televison? That should be such an easy question to answer. However, it is anything but easy. Ever since the invention of radio, several inventors discussed and even wrote about the idea of transmitting picture components over wires. But, who invented the first television is not that easy to determine.

Inventor George Carey wrote a paper about sending picture components over multiple wires. He is credited with the conceiving the idea of using parallel transmission methods. Apparently he never actually built a device capable of doing it. Inventor W. E. Sawyer suggested the possibility of sending the image over a single wire by scanning parts of the picture in succession and transmitting each part separately. Any idea yet who invented the first television?

So through the work of both of these men, the theoretical concepts needed for the transmission of pictures was firmly established. Other engineers such as Jenkins, Ives, Alananderson and Baird built devices that used spinning disks and mirrors that could scan, transmit, and reassemble moving images. Their devices worked and were based on an idea proposed in the 1880s by Paul Nipkow of Germany. The pictures were extremely crude idea yet who invented the first television.

But, it wasn�t until December 2, 1922 when Edwin Berlin, an Englishman living in Sorbonne France demonstarated a mechanical scanning device that an actual working piece of equipment was built. Berlin holds patents for the transmission of photographs by wire, fiber optics and radar. Berlin�s device took flashes of light and directed them at a selenium element connected to a device that could produce sound waves. Then the sound waves were transmited to a receiving device and remodulated back into flashes of light on a mirror. Made up your mind about yet about who invented the first television?
So, Who Invented the First Television?
Believe it or not, the controversy had just begun. Two American inventors were working on the problem of making television a reality. One was a Russian-born American inventor named Vladimir Zworykin who worked for RCA Corporation. The other was a farm boy from Utah named Philo Farnsworth who had a private wealthy backer. As one history book puts it, �Zworykin had a patent, but Fransworth had a picture.� Any idea yet who invented the first television?

That is such a simple question�who invented the first television�with such a complex answer. Zworykin patented an electronic image-scanning device called an iconoscope in 1923. His invention was basically a primitive television camera. Farnsworth developed an electronic scanning tube and demonstrated the transmission of television signals on September 7, 1927 and received a patent for his device in 1930. Fransworth�s device created and manipulated an electron beam and didn�t use any mechanical device. Who invented the first television? I don�t know�you decide.

What Year Was The Television Invented

What year was the television invented? The cathode ray tube that was used exclusively until the 1990s for television was invented in 1897 by Karl Braun in Germany. In 1884, Paul Nipkow developed a rotating-disc technology capable of transmitting pictures over a wire and called it the Nipkow disk. This was the very first electro mechanical image-scanning device and was used to transmit television until the invention of the first electronic transmission device. Any idea what year was the television invented yet?

In 1926, John Logie Baird broadcast the first transatlantic pictures using a mechanical device based on Nipkow�s system. Later Baird also developed the first color picture tube. He also started the British Broadcasting Company (BBC). Meanwhile, in the US, Charles Francis Jenkins invented a mechanical television system called radiovision. Jenkins claimed to have transmitted the earliest moving silhouette images in 1923. But, it wasn�t as clear as Baird�s transmission. So, what year was the television invented yet?

Other inventors realized the mechanical scanning devices were limited and had little room for much more improvement and they began to concentrate on using the cathode ray tube�s idea of controlling electron beams to develop and electronic scanning device that could copy and transmit images. In 1925, Vladimir Zworykin invented the iconoscope, which was a primitive television camera and in 1929, he invented a cathode-ray tube called the kinescope that could be used to transmit TV images. In 1927, Philo Farnsworth invented an electron beams scanning device that could �read� pictures when the beam�s current was varied as it played over the image. He also built a transmitter and receiving device based on the radio equipment of the time and successfully transmitted moving pictures in 1927. Has an answer to what year was the television invented yet?

It�s hard to put an exact date what year was the television invented. One reason is because it is a very complex process. No one invention could make it possible. It took several inventors many years to develop working systems. Braun created the basic component, an electronic tube that could display images. Nipkow, developed the first image scanning device. Marconi and others developed the transmitting and receiving equipment for transmission. Farnsworth invented an electronic scanning device and Zworkin invented the camera and other elements needed for recording the images. So what year was the television invented? I think it�s fair to say television was invented in the decade of the 1920s.

Watch TV On The Computer

You�re in your office. It�s time for your favorite show. You think to yourself, "Wouldn�t it be great if I could watch TV on the computer." Maybe you can. Being able to watch TV on the computer is now a reality. But does it deliver what it promises. Let�s take a look.

Here are some things to consider before committing yourself to a system that enables you to watch TV on the computer. It�s not the simple setup you might be led to think.

In order to watch TV on the computer you need to have the TV signal delivered to your PC. How you do this pretty much depends on the television system you now use.

If you are on a wire antenna or coaxial cable system, you will need a �splitter�. A splitter does exactly what the name implies. It splits one signal into two. One signal can then go to your TV. The other signal will go to your PC and enable you to watch TV on the computer. Generally, there is little noticeable loss of quality when a signal is split.

One major problem is running the cable from the splitter to your PC in order to make it possible to watch TV on the computer. Generally, the box or wall outlet used by the splitter is near your television set that may mean that the cable has to be run a long distance.

Some people use a wireless system to avoid this. It might work and you can end up being able to watch TV on the computer without a lot of hassle. But other times a wireless unit just won�t do the job.

Wireless systems are limited in the distance they can broadcast a signal. You may be able to watch TV on the computer but the picture may not be the best and you could lose your signal from time to time.

You may also need to install a TV tuner card in order to watch TV on the computer. This isn�t a difficult job but if you aren�t used to roaming around inside your PC, you will probably want this done by a professional.

And finally, the resulting image you get when you watch TV on the computer may be less than desirable, even with a quality installation. If possible, find a friend who is able to watch TV on the computer. Ask about the cost. Take a look at the quality of their picture. If you like what you see, go for it. If not, you might be better off to invest in another TV.

Watch Television Commercials

In years past, it used to be that when a television announcer said, "We�ll now pause for a word from our sponsor," everyone rushed to the kitchen. But no more. Some people like nothing better than to watch television commercials. In fact, there are so many people who like to watch television commercials that web sites are now devoted to them.

Part of this trend is due to the fact that many commercials are just downright entertaining. So being able to watch television commercials without being interrupted by programming has become fun.

For example, one web site that appeals to people who want to watch television commercials is loaded with funny Super Bowl advertising from 1998 to 2005. Every year Super Bowl advertisers try to outdo one another to create the most entertaining commercial. In fact, the competition takes on a mini-Super Bowl of its own.

There are some experts who question this trend. They feel that people who just watch television commercials for their entertainment value end up being unable to remember what the advertising is supposed to be selling. As a result, sometimes the most entertaining commercials are the ones that rank lowest in product recall.

Of course, Super Bowl advertising is not the only source of viewing by those who like to watch television commercials. There are a number of sites that include hundreds of commercials going back for several decades. They are even organized by subject or advertiser.

Then again, there is a more serious reason to explain why some people want to watch television commercials. It has nothing to do with entertainment. It has everything to do with culture.

If you really want to get a good idea of a country�s culture watch television commercials broadcast within that country. You may not understand the language but for many commercials, this is not essential. As someone once said, "Pictures are worth a thousand words."

Education is another reason to watch television commercials. Beginning writers can learn what to do and not to do when they watch television commercials. Even the bad ones have something to teach.

Although it may seem absurd to just watch television commercials, there are many good reasons for doing so. But watch out. You could find yourself obsessed with going on the Internet to watch television commercials and miss all of today�s programming. And that means you won�t be seeing any current commercials until they�re old enough to be archived on a web site.

TV Podcasts

The word podcasting was coined to describe a method of providing the audio version of a broadcast for downloading and later listening. Although podcasting was initially associated with audio programs, it has never really been limited to audio. So the term TV podcasts is just as valid a way to describe podcasting a TV program as are the terms �vodcasting� or �vidcasting�. TV podcasting is just a method of podcasting video data.

TV podcasts provide a multimedia files containing a TV show for watching on your computer or handheld device. Podcasting is a term that was coined when the use of RSS and other syndication technologies became popular for distributing audio content for mobile devices. As people begin to use the podcasting technology for files containing more than just audio, podcasting is becoming a generic term for any downloadable multimedia file.

A TV podcast is generally analogous to a recorded television series. The program provider creates a multimedia file such as an MPEG, AVI or RM encoded file containing an episode of the program they want to podcast. . The only requirement for podcasting is that the file be accessible through some known URL. Typically only one episode of the show is included in a single file. Most podcast content is published in RSS format for use in an RSS feed although that is not required. Most podcasts use RSS so their audience doesn�t miss any episodes. The viewer uses software called a podcatcher or aggregator to collect the file for later viewing. A podcatcher usually runs in the background on your computer and monitors the RSS feed and will automatically download any new episodes for the subscribed programs.

Once downloaded, the TV podcast episodes can then be played, replayed, or archived just like with any other computer file. Here are some samples of the programs available through TV podcasts:
� Tiki Bar TV - This low budget, but well-produced series has quickly become one of the most popular video podcasts.
� University of Chicago lectures � poetry lectures are available at http://poempresent.uchicago.edu/poempresent.rss and interviews with researchers are available at http://research.uchicago.edu/highlights/research.rss .
� Elizabeth Gunness - Eric Maconaghie Rogers is distributing small pieces of his latest film via TV podcast.

Thomas And Friends TV Tome

Thomas and friends TV tome airs on PBS on Sunday nights at 8 pm. It is a show about the character introduced in the children�s book series, �Thomas, the Tank Engine.� The series was created by Reverend Wilbert Vere Awdry in 1945 to entertain his son Christopher who was bedridden with measles. (In 1945, measles could cause blindness and deafness if it did not kill you first. Victims were made to stay in bed in a dark, quiet room.) After he finished the first book, Reverend Awdry made his son a wooden toy engine that young Christopher christened as �Thomas�. Reverend Awdry published a new Thomas book each year from 1945 until 1972 except for 1947 and 1971. His son Christopher later added 15 additional books to the series to make a total of 40 books. Thomas and friends TV tome is based on the books.

Thomas and friends TV tome is about a tank engine named Thomas and his friends who live on the Island of Sodor. The friends work on the railroad under the supervision of Sir Topham Hatt, the "Fat Controller." Each story is amusing, fun and contains a lesson for the young listener. Parents have been reading these books to their preschoolers since 1945 because they help to tech some important values to young children.

Britt Allcroft decided to turn Thomas and friends TV tome into a TV show on ITV in Britain in 1984. The show became an instant hit. In only a few months time, more than 8.5 millions viewers were watching Thomas. The program had actor and musician Ringo Starr as the narrator. In 1991, Starr was replaced by Michael Angelis who still narrates the show today. During the 1989 to 1993 time period both comedian George Carlin and Ringo Starr played Mr. Conductor.

After becoming a popular TV show, Thomas and friends TV tome spawned a complete line of videos, train sets, games and other related toys. Thomas starred in his own movie, Thomas and the Magic Railroad in 2000. He also has his own amusement park in Japan. Thomas celebrated his 60th birthday in 2005. The little train has come a long was with the introduction of Thomas and friends TV tome to the world.

Timeline Of Television Invention

The timeline of television invention spans many years primarily because it is such a complex process. There is no one device that can do everything that is required to record the images than transmits to a receiver and converts that back into images again. Below is an accounting of the timeline of television invention.

Timeline of television invention 1880s - The television was invented in stages by many talented scientists who each added an important piece that contributed to the finished product.In 1884, Paul Nipkow of Germany proposed and patented the world's first electromechanical television camera. Nipkow proposed a disc camera made up of two-foot diameter metal disks with holes cut into concentric circles. The holes basically cut the picture into lines that could be transmitted one dot at a time. Light sensitive selenium behind the perforated disk would capture the moving image. This camera became known as the Nipkow Disk.

Timeline of television invention 1890s - 1897, Karl Braun invented the cathode ray tube, the basis of every TV set until the development of LCD screens. In 1890, Boris Rosing used a mirror drum device similar to the device a photocopier uses today as a camera to transmit black-and-white silhouettes of simple shapes to a cathode-ray tube as a receiver. 1907

Timeline of television invention 1920s -American Charles Francis Jenkins used "prismatic rings" as a device to replace the shutter on a film projector and eventually became the basis for his first radiovision broadcast. He claimed to have transmitted the earliest moving silhouette images. In 1926, John Logie Baird transmitted the world�s first television picture using a mechanical system based on Nipkow�s disks that produced poor quality images and was eventually replaced by an electronic system. John Logie Baird is still widely hailed as the 'father' of television.

Timeline of television invention major controversy - In 1923, Vladimir Zworikyn received a patent for the iconoscope that was a primitive video camera. He spent the next six years researching photoelectric and receiving tubes and demonstrated his all-electronic television receiver using a "Kinescope", which was a special kind of cathode ray tube. In 1927, at the age of 21, Utah born Philo T. Farnsworth developed the world's first all-electronic system of television. He got the idea for his "image dissector tube" while watching a field being plowed into "furrows". He would later sell his patents after a long and bitter court battle with RCA.

Timeline of television invention 1940s - In 1948, or Community Antenna Television or Cable TV, was first introduced in Pennsylvania by John Watson. Watson developed the first cable system when he placed one antenna on top of his appliance store and another on top of a mountain and transmitted them back and forth. Watson�s invention of the cable television industry brought television to people who lived in areas that were unable to receive conventional broadcast signals.

Timeline of television invention 1950s - Next CBS broadcasts color using its non-compatible system. The one-hour program, called Premiere, featured Ed Sullivan and other CBS stars, and is carried on a five-station East Coast CBS-TV hookup.

Timeline of television invention 1960s - 1960, inventors at Bell Labs (AT&T) began development of a satellite communications system called Telstar. With the satellites in random geosynchronous orbits, 55 satellites can provide service 99.9 per cent of the time between any two points on earth.

Timeline of television invention 1990s and beyond - In 1997, Wide-screen HDTV went on sale. In 2000, TV became available on the Internet. Who know what changes will occur in the timeline of television invention as we go forward.

Television Shows From 1963

Some people consider television shows from 1963 part of the golden age of television. I just barely remember some of these programs, but the ones I have seen in reruns were pretty good and could be watched by almost every family member. Certainly there was less bad language, sex and violence in television shows from 1963.

In 193 there were almost 52 million households with TV sets. It�s hard for me to imagine anyone not owning a TV. I can understand not watching a lot of TV, but not owning one?
The following is a list of the top 30 television shows from 1963:

Top 10 television shows from 1963:
1. The Beverly Hillbillies � comedy about a family of hillbillies living in a Beverly Hills mansion
2. Bonanza � western about a wealthy rancher and his sons
3. The Dick Van Dyke Show - sitcom about a TV writer
4. Petticoat Junction � comedy about a family who owned a hotel near a train station
5. The Andy Griffith Show � sitcom about a rural town�s sheriff
6. The Lucy Show - a spin off of I love Lucy
7. Candid Camera - the original was just like the current version
8. The Ed Sullivan Show � a variety show where multiple entertainers performed each week
9. The Danny Thomas Show � sitcom about a family
10. My Favorite Martian � a comedy about an eccentric Martian visiting earth

Number 11 to 20 television shows from 1963:
11. The Red Skelton Show - a comedy starring Red Skelton
12. I've Got a Secret - a game show where celebrities tried to guess contestants secrets
13. Lassie � story about a boy and his dog. The dog was super smart and tended to always save the day
14. The Jack Benny Show - a variety show hosted by comedian Jack Benny
15. The Jackie Gleason Show - A variety show hosted by Jackie Gleason
16. The Donna Reed Show � a family sitcom.
17. The Virginian � a western drama.
18. The Patty Duke Show � a sitcom about cousins who looked like twins
19. Dr. Kildare � a medical drama.
20. Gunsmoke � a western that lasted 25 years.

Numbers 21 to 30 television shows from 1963:
21. Walt Disney's Wonderful World of Color - just what it sounds like.
22. Hazel - a sitcom about a maid and the family she worked for.
23. McHale's Navy � a comedy about navy men.
24. To Tell the Truth � a game show
25. What's My Line - a game show where celebrities tried to guess contestants occupations.
26. Perry Mason � a courtroom drama.
27. My Three Sons - comedy about a father and his sons
28. The Fugitive � the series that inspired the blockbuster movies a few years ago
29. The Adventures of Ozzie and Harriet - a family sitcom
30. The Danny Kaye Show - a variety show hosted by actor Danny Kaye

The television shows from 1963 are not all that different from what offered today. The programs are more explicit and adult oriented. But you need to remember there were only a few channels back them so the television shows from 1963 had to be more family oriented than is necessary with hundreds of channels and a special network for almost every topic.
