Last year, LCD TVs made up about 50 per cent of global TV sales. That’s a huge number. Not bad for a technology that’s only 40 years old or so…
Originally, plasma display technology was developed back in the 1960s as a screen for the PLATO teaching computer system. It was a simple, monologue display of the brightest orange that measured in at about an inch thick. Back then, nobody had any idea that plasma would some day lead a revolution into the lounge room…
While it’s quite fun to look back at the history of television this month, it also helps to point out just how good we’ve got it today.

That’s what it was like (except without the “hundred-odd”) before the remote control was invented in 1950.
Colour TV broadcasts began in Australia in March 1975, a mere 34 years ago. But the first demonstrated colour transmission in the world happened way back in July 1928, by a gentleman by the name of John Logie Baird.
It may have been Scotsman John Logie Baird who changed the world by broadcasting a moving image using his mechanical Televisor device, but a lot of the credit for the fully electronic televisions we watch today goes to Hungarian Kálmán Tihanyi, who pioneered a fully electronic system and the development of the use of cathode ray tubes.
Has there ever been a technology as pervasive as the television? Ever since John Logie Baird demonstrated his mechanical device that showed moving images at 12.5 frames per second in 1926, the world has had an ongoing love affair with TV. And all this month, we’re going to be looking back at how the technology that we all take for granted grew and developed into the LCDs and plasmas we use today.
