In , the program was thought to be broadcast only to four television sets. Not Not 4, Thus, we have some ambiguity and debate over whether this was actually the first television program. The first television station in America started broadcasting in For the first 13 years of its existence, television remained blissfully commercial-free.
The first commercial broadcast in America did not take place until July 1, , which is when the first American advertisement aired.
The ad was for a Bulova watch and lasted for 10 seconds. It aired on NBC. Color television traces its roots as far back as , when a German inventor received a patent for color television. However, that inventor did not actually have a working color television — it was just a patented idea. A conceptualized color television system appeared in from inventor Vladimir Zworykin. However, this system was never converted into reality.
All attempts to convert it into reality did not succeed. Color television was placed on the backburner for about 20 years. In , the idea of color television was renewed in earnest. As TheHistoryOfTelevision.
Black and white television was thought of as old and it was time to do something new. This is when color television systems first began to be considered seriously. CBS was the first company to create a color television set. Thus, it was not compatible with black and white TV sets in use across America. Unfazed, RCA continued to develop their own color television system that would be compatible with its customers RCA sets.
Few people owned color TV sets between and However, starting in , color TV programming was broadcast across America, leading to a surge in sales of color television sets.
Between the s and s, television turned from a niche technology into a critical form of communication found in living rooms across the nation. In , Zworykin demonstrated his all-electronic television system at a convention of radio engineers. Born into a poor Jewish family in Minsk, Russia, Sarnoff had come to New York City as a child and began his career as a telegraph operator. April 30, , New York City: This is the scene viewed on the television receivers in the metropolitan area, as the National Broadcasting Company inaugurated the first regular television service to the American public telecasting the ceremonies marking the opening of the New York World's Fair.
Later, viewers heard and saw President Roosevelt proclaim the fair open. Sarnoff was among the earliest to see that television, like radio, had enormous potential as a medium for entertainment as well as communication.
Named president of RCA in , he hired Zworykin to develop and improve television technology for the company. Meanwhile, an American inventor named Philo Farnsworth had been working on his own television system. Farnsworth, who grew up on a farm in Utah, reportedly came up with his big idea—a vacuum tube that could dissect images into lines, transmit those lines and turn them back into images—while still a teenager in chemistry class. The U. Though viewed by many historians as the true father of television, Farnsworth never earned much more from his invention, and was dogged by patent appeal lawsuits from RCA.
Once the switch took place, many older analog TV sets were unusable without a cable or satellite service or a digital converter. These companies were eager to gain access to the analog spectrum for mobile broadband projects because this frequency band allows signals to travel greater distances and penetrate buildings more easily.
Around the same time the U. High-definition television , or HDTV, attempts to create a heightened sense of realism by providing the viewer with an almost three-dimensional experience. It has a much higher resolution than standard television systems, using around five times as many pixels per frame. However, as with most new technology, prices dropped considerably over the next few years, making HDTV affordable for mainstream shoppers.
HDTV uses a wide-screen format with a different aspect ratio the ratio of the width of the image to its height than standard-definition TV. The wide-screen format of HDTV is similar to that of movies, allowing for a more authentic film-viewing experience at home. As of , nearly half of American viewers are watching television in high definition, the fastest adoption of TV technology since the introduction of the VCR in the s Stelter, The new technology is attracting viewers to watch television for longer periods of time.
According to the Nielsen Company, a company that measures TV viewership, households with HDTV watch 3 percent more prime-time television —programming screened between 7 and 11 p. The same report claims that the cinematic experience of HDTV is bringing families back together in the living room in front of the large wide-screen TV and out of the kitchen and bedroom, where individuals tend to watch television alone on smaller screens. However, these viewing patterns may change again soon as the Internet plays an increasingly larger role in how people view TV programs.
The impact of new technologies on television is discussed in much greater detail in Section 9. Since , the amount of time the average household spends watching television has almost doubled. Please respond to the following writing prompts.

Figure 9. Mechanical Television versus Electronic Television From the early experiments with visual transmissions, two types of television systems came into existence: mechanical television and electronic television.
Color Technology Although it did not become available until the s or popular until the s, the technology for producing color television was proposed as early as , and was demonstrated by John Logie Baird in The Golden Age of Television Figure 9. The Rise of Cable Television Formerly known as Community Antenna Television, or CATV, cable television was originally developed in the s in remote or mountainous areas, including in Arkansas, Oregon, and Pennsylvania, to enhance poor reception of regular television signals.
The Emergence of Digital Television Following the FCC standards set out during the early s, television sets received programs via analog signals made of radio waves. Key Takeaways Two key technological developments in the late s played a vital role in the evolution of television: the cathode ray tube and the scanning disk.
The cathode ray tube, invented by German physicist Karl Ferdinand Braun in , was the forerunner of the TV picture tube. The scanning disk, invented by German inventor Paul Nipkow, was a large, flat metal disk that could be used as a rotating camera.
It served as the foundation for experiments on the transmission of visual images for several decades. Out of the cathode ray tube and the scanning disk, two types of primitive television systems evolved: mechanical systems and electronic systems.

It served as the foundation for experiments on the transmission of visual images for several decades. Out of the cathode ray tube and the scanning disk, two types of primitive television systems evolved: mechanical systems and electronic systems. Mechanical television systems had several technical disadvantages: Low resolution caused fuzzy images, and the use of a spinning disk limited the number of new pictures that could be seen per second, resulting in excessive flickering.
By , all mechanical television broadcasts in the United States had been replaced by electronic broadcasts. Early televisions were expensive, and the technology was slow to catch on because development was delayed during World War II. Color technology was delayed even further because early color systems were incompatible with black-and-white television sets. Following the war, television rapidly replaced radio as the new mass medium.
Since , several key technological developments have taken place in the television industry. Color television gained popularity in the late s and began to replace black-and-white television in the s. Cable television, initially developed in the s to cater to viewers in rural areas, switched its focus from local to national television, offering an extensive number of channels.
In , the traditional analog system, which had been in place for 60 years, was replaced with digital television, giving viewers a higher-quality picture and freeing up frequency space. As of , nearly half of American viewers have high-definition television, which offers a crystal-clear picture in wide-screen to provide a cinematic experience at home.
Exercises Please respond to the following writing prompts. Prior to World War II, television was in the early stages of development. In the years following the war, the technical development and growth in popularity of the medium were exponential.
