This new tecnology has been used in movies like ''Avatar'' and ''Up'' and the people loved it, so they decided to bring it to the home of the persons, for ours TVs.To make it possible, some adaptations were made, one of that was the fact that you just can see 3D pictures if you use a special glasses witch worths very expensive and sometimes it's unconfortable for some people use it.Other problem it's the highs prices, this televisions cost much more than the common ones,and this can make the sale isn't great, because the cost to make it is much more bigger.And some persons have headache watch 3D images, and that's a really a major problem, because the health of people is always in the first thought.
Althought all this problems there're a lot of companies are investing heavily in the manufacture of this product, like Samsung, LG Panasonic, Sony and Toshiba, because they thing that in na near future,in others words, in some years it will be very common and will be very lucrative and with the World Cup the sales of TVs with increase and can make the popularization of it around the Wolrd.
