Nowadays, with a lot of us owning high-definition, cable-ready flat-screen TVs, we seem to be take televisions for granted. But take time to think how amazing television has evolved through the years since it was invented. Way back then, having a “window to the world” in the comforts of one’s home was just a dream for inventors. But eventually, the whole United States have been fascinated, entertained and informed through the television, since it was invented about 75 years ago.
The liqud-crystal-display televisions (LCD TVs) are remarkably thinner and lighter than cathode ray tube (CRT) televisions. Although LCD TVs first emerged in the early 80s, it was in 2007 where they surpassed the sales of the CRT TVs for the first time.
One of the grandaddies of the television is the first transmitter invented by Italian engineer Guglielmo Marconi. It successfully sent the world’s first radio message across the Atlantic. The “radio” did not send music or voice like the radio we know today. Rather, the radio received buzzing sounds from the spark gap transmitter that relayed a message using the Morse code.
Portable televisions came as early as the 1950s but they were too heavy to be carried. One of the earliest portable TVs (if not the first) was the 1955 Ecko TMB valve TV, complete with a handle. The first “miniature TV” was the Sinclair MTV-1 which was introduced in the market in 1970. Only a few years later up to the 1980s, companies such as Panasonic and Sony began to introduce handheld TVs in the consumer market.
According to many sources, the first OLED TV (curved screen TV) introduced in the consumer market was released by LG in 2014.
One of the truly “micro” portable televisions to come out in history is the Philco “Safari” portable television in 1959. It was powered by a small battery and run through transistors.
Introduced after World War II, the RCA 630-TS became an immediate hit. It was considered a high-tech, large-screen television during its time, measuring 10 inches and housed in an sleek cabinet.
Throughout the years antennae as well as satellite dishes have appeared and gone depending on the changing course of technology.
Samsung’s UN1059 TV, released in 2015, is a 105-inch screen monster. Carrying a retail price of “only” $119,999, it was touted as the most affordable 4K TV yet (that is, if you are a millionaire).
SMPTE color bars, also known as a test pattern, is television test signal. These color bars are usually shown when the transmitter is operating but no available program is being broadcast. It is also common when we are about to play videotapes, video CD’s or DVDs, so the color bars are pretty much a standard thing.
Color bars are used for calibrating equipment for broadcasting, recording or playing back videos. These color bars help the user to adjust the colors on their sets to correct and accurate hues recorded on tape.
What’s so unique about this television is that its screen can be swiveled. Yep, it was the first “swivel” TV to be introduced into the market. However, its slow sales eventually led Philco to file bankruptcy in 1960.
This tablemodel TV was released for the Czechoslovakian market in 1953. It was made for the first national channel, with inter-carrier audio processing, 11 FM circuits, and an AC supply of 120-220 volts.
Americans were quickly enchanted by this apparatus — and it is still evident in this high-tech, digital age. During the 1950s, there were around six million households who had television sets, and by the 1960s that figure astoundingly increased to about 60 million.
John Logie Baird is commonly credited as the one who invented the world’s first working television system in 1926, as well as the first colored television system. Here in this picture he is working with his televisor equipment and his dummies.
Television has come a long way for many decades, from thick, heavy-glass CRT monitors to flat, curved high definition flat screen TVs.
Dubbed as the “Father of Television,” Russian inventor Vladimir Zworykin’s work is clearly undisputable. He was responsible for creating the all-important inescope, more familiarly known as the cathode-ray tube.
