There was a time in the not too distant past when buying a new television was a pretty simple task.
 The truly main concern that one had in doing so was to figure out just how big one wanted it to be.
 Well, things have changed greatly quite recently with the introduction of new technology into the home television viewing experience.
 So, now the major question to ask is what type of technology would one like to have.
There are now a range of choices in the purchasing of televisions that was previous unheard of.
 And, there are main two genres that have been available.
 There are plasma televisions.
 There are LCD televisions.
 A plasma television is basically one that uses individual gas-filled pixels to create an image on the screen.
 An LCD (liquid crystal display) television is simply one that liquid crystal-filled cells with a CCFL (cold cathode fluorescent lamp) as their backlight to create an image on the screen.
  Samsung Electronics recently introduced what it calls a "new" technology that it calls LED light emitting diode) televisions into the market.
 The talk is that LED televisions are superior than both plasma and LCD televisions.
 But, true LED televisions are the giant televisions that you see in sports stadiums that are made of a layer of extremely bright LED lights.
 What Samsung has actually introduced is a more advanced form of LCD television that is not lit by CCFLs, but rather by LEDs.
While Samsung has used some cunning to market its LED televisions that actually do give one a better picture than plasma and LCD, it should be noted that its sales pitch is taken from the success of the Sony XEL-1 OLED (organic light emitting diode) TV which are real LED televisions.
 The Samsung LED DLP HDTV, for instance, is an improvement over existing technology in three key areas.
 The first is that it picture quality is superior because of its color range and quality.
 The second is that is is a green TV in that it uses less energy.
 The third is that it was ultra thin and quite attractive.
