The latest 3D technology seems to be a product of modern millennia, which has been brought to the pinnacle of popularity by James Cameron's "Avatar". However 3D has been left unnoticed by electronic consumers during the 1990's. This same technology has been utilized by cable TV to gained ratings.
TV in 3D has been the newest offering of televisions manufacturers to keep people buying TVs. But there has been reluctance and doubt if TV in 3D with its expensive price tag will click among consumers. In the past two years, consumers had been upgrading their digital TVs, and it may seem impractical to spend another dime to upgrade for a new TV set.

But Samsung Electronics, Sony, LG Electronics and Panasonic prove to be unstoppable, as they released their versions of TV in 3D at the consumer's electronic show held in Las Vegas. Clips of "Journey to the Center of the Earth" and Walt Disney Pictures' animated film "Bolt" have been presented by Panasonic in their 103-inch, plasma 3D. The NBC's broadcast of the 2008 Summer Olympics in Beijing has also been shown in high definition 3D.
Aside from the fact that it may not be as practical nowadays, TV in 3D has its' in own share of drawbacks. The fluorescent lighting might elicit flickering effect, and direct exposure to the sun may greatly affect the 3d glasses. Simply consumers couldn't perceive 3d images without the 3d glasses. The two Polaroid filters within the 3d glasses allows some image to pass though one filter, while sending some images into the other which is the reason why depth is seen.
Needless to say the image looks blurry without the glasses. Some claim that when viewers of TV in 3D are exposed to certain flashing images or lights in television pictures or video games, they might experience epileptic seizure or stroke. Motion sickness, perceptual after effects, disorientation, eye strain, and decreased postural stability may also manifest after viewing films in 3D mode. Some professional advice that people, who are in poor physical condition, have been drinking alcohol and those who lack sleep should not watch 3D. It may cause nausea and headaches. Extended 3d TV viewing is also not recommended.
Television manufacturers admitted that TV in 3D is still in its early phase of development. Some technical improvements are still in the process. They are keeping their high hopes that consumers will be lured in bringing 3D movie theater experience in their homes in spite of some issues in its hefty price and physical after effects.
