It has been almost a century since the first television (which is commonly abbreviated as TV) was invented and it has gone through many kinds of transformation. At first, TV had a very small, colorless screen with a large case that included large speakers. So, if you’re currently wondering about how to clean TV screen or how the TV that you have now was in the past, then it’s better to know more about the evolution of TV from time to time.
Early years (1920s-1940s)
In the early years of the invention of TV, its technology was still quite simple. In terms of appearance, TVs in that era had large cases, were heavy and bulky, and had very small displays. However, in the 1930s, TVs started to use electricity to power them up. However, they started to be generally recognized as electronic appliances in the 1940s with a typical design of a wooden case with a small TV display at the center of it.
Golden era of TV (1950s-1980s)
After the booming TV sales in the 1940s, manufacturers started to make many improvements in this era. One of the most notable improvements is the invention of remote controls that could change volumes and channels from a certain distance in the 1950s. Another quite notable improvement is the broadcasting of color signals in the same era. Then in the 1960s, color TVs became very popular and the screen sizes became bigger. This condition continued until the 1980s with many improvements in terms of design and size.
Flat screen era (1990s-2000s)
One of the most significant changes in the history of TV is the change from the convex screen TV to the flat screen TV. However, although TVs back in the 1990s had flat screens, they still used tubes. But in the 2000s, manufacturers started to produce LCD TVs, leaving the tube TVs behind due to how inefficient they were in terms of size and power consumption.
Smart and high resolution TV era (2010s-present)
These days, TVs have become quite different from those in their early years. Now, smart TVs with OLED panels and Android OS that can access the internet are everywhere. Not to mention that those TVs have very high resolutions up to 8K. The leap in the resolutions will give the audience clearer visuals. Besides, there are also curved TVs that are favored by those video game and movie freaks. Those TVs cover the disadvantages of flat screen TVs that provide poor visuals when viewed from certain angles, especially those that have very large screen sizes such as the ones above 70 inches.
