The history of the television is a very interesting subject for those who wish to know more about where the idiot box came from. The word television' was coined on the 25th of August 1900 at the International World Fair in Paris. We all know how the television serves to entertain us. It has become an integral part of our lives because of the multitude of functions it can perform for us. In the mornings it informs us about the happenings of the world around us, it shows the business man exactly where he stands with regards to the world of commerce, in the afternoons it entertains the home makers, in the evening the kids and at night the whole family. It truly is an amazing device that has traveled long and far to reach the stage at which it is today.

You will get the hardware from your cable operator and it will cost you just a little more than your regular cable box connections. The charges would be in the vicinity of $ 800 for the unit and thereafter a separate $ 13 per month fee for usage.

One difference that crops up between the two has its roots in the way that the image is displayed. When you look at the two screens displaying the same image to you, you will realize the image on the plasma screen will be much better than the LCD. [...]
[...] The high definition TV has many more dots compared to other TV's and they are set in squares and are spaced closer together and are smaller in size. Sometimes there can be up to four times as many pixels in the same areas in a HDTV than there are in a regular TV leading, eventually, to a sharper and more defined image. In other words you will get to see four times as much detail as you would on any other TV. [...]
[...] The next thing I will talk about is the comparison between the high definition TV and the standard definition TV and also try and explain how why they differ. The concept we discussed earlier, that of ‘i' and that of also comes into play here as when we talk about an HDTV we are actually saying that the TV's resolution must either be 1080i or 720p.
