It effectively turned day into night. And how it shaped the world now. Time travel with us every week on the ThruLine podcast from NPR. The development of a working television that could receive moving images via electromagnetic waves and then display them on a throughline podcast from NPR. an electronic device, took many different innovations before they could all be packaged together in a working product. The first steps which led to the development of a television go back far earlier than most people realize. It all started with the ability to send a facsimile of an image over a telegraph line. A system for sending an image via telegraph was developed shockingly

early after the telegraph itself. The first patent for transmitting an image over a telegraph line was filed in 1843 by the Scottish inventor Alexander Bain. The quality of the image was extremely poor, and it was incredibly slow, and it really wasn't practical. In 1884, a German student by the name of Paul Gottlieb Nipkow invented a device known as a Nipkow disc. The Nipkow disc was an extremely important device that allowed images to be scanned. The disc was just a circular disc with holes in it in a spiral pattern. As the disc was spun, light would pass through the holes which could take.

a slice of the image which could then be sent to a light detector. If you remember back to my episode on solar power, it was discovered in the 19th century that the element selenium was discovered to be photoconductive. Not only was this really important in the development of photoelectric cells, but also in light receptors, which became used in what was then known as mechanical television. The word television was first coined in 1900 by a paper by the Russian scientist Konstantin Persky, which was delivered at the Paris World's Fair. The word fit with the other inventions of the era, including the telegraph and the telephone.

The first working system which integrated all of these components was demonstrated in 1909 in Paris. They created a grid of 64 selenium photoreceptors, or as we'd say today, it was an 8x8 pixel image. It could instantly transmit a very simple image over wires, which for the purpose of the demonstration was nothing more than the letters of the alphabet. In 1908, the Scottish engineer Alan Archibald Campbell Swinton proposed that a cathode ray tube could replace the Nipkow disc as both a transmitter and receiver to create what he called a distant electronic vision. In 2011, the first images were transmitted using a cathode ray tube, but again, this was more of a proof of concept. It wasn't producing real images. The cathode ray tubes were very crude at this point, but they improved dramatically over the next several years. In 1926, the Russian-American scientist Vladimir Zoriken, working for Westinghouse, developed a cathode ray tube that could display images.

It was dubbed the iconoscope. Here, I should briefly explain what a cathode ray tube or CRT is, because it's central to television for the next 80 years. A CRT is basically a stream of electrons that is shot out of a tube towards a photosensitive screen. Initially, it was made out of selenium. A coil inside the tube influences the stream of electrons, which allows the stream to create images on the photosensitive screen. In 1926, a huge leap was made when Scottish inventor James Baird demonstrated what is considered the first true television to a group of 50 scientists in London. In 1927, he managed to transmit a television signal over 438 miles of telephone lines from Glasgow to London. And in 1928, he sent the first transatlantic television signal to New York and the first transatlantic television signal to New York,

and the first wireless signal to a ship at sea. Also in 1928, the Federal Radio Commission granted an experimental amateur license to Charles Jenkins, call sign W3XK, to broadcast an experimental television signal from his home in the suburbs of Washington, D.C. His signal broadcast movies with a resolution of 48 lines. In 1929, Vladimir Zoriken showed his system to the president of the Radio Corporation of America, or RCA, David Sarnoff. Sarnoff's RCA was one of the biggest radio companies in the world, and he saw the potential for broadcasting televised images. However, neither Baird nor Zvorican are considered the father of modern television.

That distinction belongs to an American vendor who grew up on a farm in Utah and didn't even have electricity at his house until he was 14. Philo Farnsworth. In 1927, at the age of 21, he developed a prototype of his own television system, and according to legend, He originally came up with the idea while in a high school chemistry class. His innovation was what he called an image disector. Basically, he broke down an image into lines. Those lines were then transmitted and displayed by a cathode ray tube which rapidly scanned those lines across the screen.

The idea of scanning lines of an image became the basis for all analog television, and it's still the basis for digital displays today. Being a kid fresh off the farm, he was immediately sued by RCA for patent-infringed but he famously won his case with the U.S. Patent Office in 1934, and he was awarded $1 million in damages from RCA. It didn't stop RCA from appealing the case and further harassing him, but Farnsworth had won. RCA adopted the scanning line system, and they introduced their television system to the world at the 1939 World's Fair in New York.

The RCA broadcast division, known as the National Broadcasting Company, or NBC, broadcasts the opening ceremony, and a speech by President Franklin Roosevelt. There were only 400 television sets in existence that could receive the broadcast, but there was an estimated audience of 5,000 people who all huddled around to watch. The adoption of television slowed to a crawl during World War II. The war effort prioritized cathode ray tubes for military use. This was the first time there was widespread adoption of CRTs, primarily for things like radar and oscilloscopes. Most television stations either stopped broadcasting during the war completely,

or limited themselves to just four hours of broadcasting a week. The very first TV sets were tiny. The screens would only have been about five, nine, or twelve inches, and the average smartphone screen today would actually have been bigger. They were also extremely expensive. TV sets in the 1940s cost between $2 to $600, and this was at a time when the average American salary was around $1,300 per year. In the early 1940s, NBC rival company, the Columbia Broadcasting System,

or CBS began to air their own television programs. In an effort to avoid competing standards, the Federal Communications Commission adopted a nationwide television standard in 1941 of 525 lines of resolution with a refresh rate of 30 frames per second. In Europe, 625 lines of resolution was adopted as a standard, a standard which, surprisingly, was first established by the Soviet Union. Once the war was over, television exploded in popularity. In 1948, the popular radio show that Texas star theater starring Milton Burrell began broadcasting on television.

Burrell, being one of the first TV stars, was given the nickname Mr. Television. By 1949, there were one million television sets in the United States, and a year later, there were six million. By 1955, half of all American households had television sets. Of course, all the television sets at this point had one thing in common. They were all black and white. Ever since people began experimenting with television, people were thinking about sending color images. One of the earliest demonstrations used three Nip Cow wheels, one for each primary color, red, green, and blue. However, mechanical televisions weren't practical, and with everyone owning electric televisions after the war,

the quest was on to find a practical color television system that was compatible with the current existing black and white TVs. The National Television Systems Committee, or NTSC, developed a compatible color TV system, which was approved by the federal communication system in 1953. The NTSC system separated the brightness information, which could still be used in black and white, and the color information. Initially, color TV signals would have had a much lower resolution than the same black and white signal. The first color television show was made by NBC on August 30th, 1953. It was an episode of the children's program Kukla Fran and Ollie, but it was only shown at the NBC headquarters.

A full public broadcast of a color television program was first made on October 31, 1953, and it was of the opera Carmen. Public adoption of color television was much slower than the initial adoption of black and white TV. Color television sets wouldn't outnumber black and white TV sets in the United States until 1972. The next big innovation in television came with the adoption of cable TV. As I mentioned above, wires were initially used for television before wireless signals. The earliest use of cables to send actual television signals was in the 1940s, when it was used to bring television to homes and mountain valleys in Pennsylvania that couldn't get a signal. However, it soon became obvious that delivering television by coaxial cable had many advantages over terrestrial broadcasting. You could deliver way more channels, and you wouldn't have to worry about the government licensing of the airwaves.

It allowed for the creation of cable-only networks like HBO, CNN, and MTV. Cable penetration reached 50% of the United States. States in 1988. Back in the mid-70s, my family was one of the very first to get cable TV in our neighborhood. I remember they had a weather channel that consisted of nothing but a camera pointed at a thermometer. With the rise of cable networks, many of them also broadcast to local cable companies via satellite, and soon customers were able to pick up those signals if they had a large KU-band satellite dish. As TV entered the 90s, the limitations of the television standards were becoming apparent. For starters, television was broadcast in a 4-3 aspect race, and, and, you know, and

whereas movies were often shown in a more widescreen format such as 16 by 9 and sometimes even wider. In the 1960s, NHK, the Japanese Broadcasting Corporation, began experimenting with higher quality television. They rolled out a system with 1,125 lines of resolution in the 1970s, and high-definition systems were being demonstrated throughout the 1980s. High-definition systems were slow to catch on similar to color TV. It was a chicken and egg problem. No one wanted to buy a high-definition TV when there was no programming, and no one wanted to make programming if no-one-owned high-definition TV sets. Also, these first HD systems were all analog, which required much more bandwidth than regular TV. Analog HD was eventually abandoned in favor

of a digital signal. Digital signal could be compressed, which saved bandwidth. The first public HD broadcast was in 1998, and it was the launch of the spatial discovery carrying John Glenn to orbit. This is also when the first HD television sets went on sale for between $5,000 to $10,000. Once HD programs and television sets were in production, it only took 12 years until 2010, until half the American population was watching high-definition TV, which is defined to be at least 720 lines of resolution progressively scanned, or 180 lines which are interlaced. Not only were television standards out of date, but CRT televisions were extremely heavy. A 32-inch CRT was a beast of a television set and weighed so much

that it could barely be moved by one person. And I know this because I've had to do it myself. The first CRT replacement were plasma television sets. The first practical plasma monitor was developed at the University of Illinois in 1964. The primary benefits of plasma monitors were that they were very thin and they could be made very large. The problem was they were very expensive and not very energy efficient. The last plasma displays were made in 2015.

What worked far better as a flat screen television were LCD screens. LCD screens are cheaper, lighter, not as hot, and are far more energy-efficient. These screens are now in everything, and I'd be willing to bet, in whatever device you happen to be listening to this right now, there is an LCD screen on it. Of course, if 180 lines of resolution is good, then more must be better. In nearly 2000, standards were developed which would quadruple the image resolution of high-definition systems at the time. The standard which was adopted for TV goes by 4K, and there are close to 4,000 lines of resolution. The 4K format is technically 3,840 rows by 2,160 columns.

50% of the U.S. market owned television sets capable of showing 4K content by the year 2020. There is now also talk of 8K and 16K video formats. However, these resolutions are so high that it's almost impossible to notice the difference unless you happen to have your face just a few feet from the screen. The thing which has been increasing is the size of television sets. Where 32 inches was large for a CRT television, 32 inches would be considered small for an LCD television. I've seen 85-inch televisions on sale that are only $1,200.

But if you're willing to shell out over six figures, you could buy one that's over 300 inches. The worst TV set you could buy today is a glorious masterpiece compared to what you could buy just 20 years ago. It's cheaper, lighter, more energy-efficient, and with much higher image quality. Television has come a long way in 100 years when it was nothing more than light being captured
