For nearly a century, televisions have populated most American homes. Since the invention of the first electronic television in 1927, a lot has changed regarding the design of this influential electronic device. The progression of televisions has occurred so quickly that each decade since its creation has brought substantial new developments that have revolutionized the TV viewing experience. To learn more about how the television has evolved throughout the years, continue reading.
During the early stages of television development, two types of systems emerged: mechanical television and electric television. John Logie Baird invented the mechanical television in 1926. It used mechanical rotating disks to scan moving images into electrical impulses. A cable would then transmit these impulses to a screen which appeared as low-resolution, light and dark patterns. Despite the relative success of this system, it had many limitations. Namely, it couldn’t produce more than 240 lines of resolution, resulting in fuzzy images. In addition, the spinning disk used greatly limited the number of pictures that one could view per second. This created a distracting flickering effect. Such limitations created a need for a more-evolved television system and paved the way for the electric television.
The early stages of electric television
The initial electric television system transmitted the picture using an electronic beam that scans a picture’s horizontal lines and almost instantly reproduces the image. Throughout the years, the electronic model gradually replaced mechanical televisions due to its superior features and capabilities. Unlike mechanical televisions, electric systems were more compact, had fewer visual limitations, better picture quality, and less noise.
A 21-year-old named Philo Taylor Farnsworth invented the first electric television in 1927. However, his invention wasn’t commercially available in America until 1939. Even still, less than 1,000 TV sets were in use around the country. It took another decade for electric televisions to gain substantial popularity. This delay is largely due to World War II which halted the production of televisions to focus more energy on developing radar technology. It wasn’t until 1948—after people settled back into their regular lives and the American economy regained its strength—that the television became a mainstream feature.
Color, controllers, and cable change the game
In 1953, Americans witnessed the invention of color television. However, it didn’t become standardized until the late1960s when TV networks adapted to the new format. By 1978, manufacturers stopped producing large Black and While television consoles. As color televisions rose to prominence, the invention of the remote control followed. It allowed for a more convenient viewing experience. During this decade, another huge transformation occurred—cable television rose to eminence and widely expanded home entertainment options. This popularity began with networks such as HBO in 1972 and expanded throughout the decade to include Nickelodeon, MTV, and Comedy Central.
TV accessories emerge
While there wasn’t much innovation associated with the TV system in the 80s, inventors placed a greater focus on television accessories. Accessories such as the VCR system and game consoles became increasingly popular during this time. Although people invented such systems many years prior, they didn’t become popular until the 80s. The VCR system especially changed the way people watched TV by allowing them to record their favorite programs and watch them on their own schedule.
A couple of decades later, a new TV accessory reigned supreme for creating the ideal home theater experience; the DVD player. The launch for this video player occurred in 1997. It didn’t remain on-top for that long, however, as new innovations posed steep competition. Following the DVD’s emergence, updates started occurring more frequently. Fewer than ten years after the DVD player gained prominence, new video players such as HD DVD and Blu-ray emerged, fighting for the top spot in high definition viewing.
Digital defeats analog
In the past, TVs used to receive programs via analog signals composed of radio waves. People favored this method for over 60 years until digital televisions came into play and revolutionized the TV experience once again. Samsung was the first television company to mass-produce the world’s first digital TV in 1998. Unlike analog televisions which often had poor picture quality due to static and distortion, digital TVs had much clearer images. They more closely resembled the quality of film shown in movie theaters. The poor quality of analog TVs became exaggerated as screens got increasingly bigger, and by 2009, all networks made the switch to exclusively producing a digital signal. Thus, businesses began to phase out analog TVs.
LCD and plasma screens
During the early 21st century, television design became increasingly advanced. Replacing standard CRT TVs, technologies such as Plasma and LCD moved out of their experimental stages and became the new market leaders. Such advancements in TV technology allowed manufacturers to produce TVs with larger screens and better picture. As a bonus, they were also much thinner and less bulky than older editions.
TVs get an education
Advances in high-speed internet greatly impacted the world of television. As more people began posting shows online without the broadcaster’s permission, they decided to make their programs available online as well. Streaming services such as Netflix, Hulu, and iTunes have revolutionized the way people view television programming. In doing so, they also created a need for a new television design. Enter Smart TVs. The design of these televisions allowed them to connect to the internet so that individuals could diversify their viewing options. Today, TV technology provides us with a variety of TV show and movie options that we can view quickly and easily by renting or streaming them through several platforms.
The rapid development of televisions has brought on incredible innovations that have enhanced our viewing experience. This fast-paced evolution, however, also means that consumers are quickly replacing TV models for newer editions. As such, finding replacement parts for older TV models can be difficult.
