If you bought a new television set in the last two years, it is likely that you thought your new TV would not be outdated anytime soon. Then, a 3D movie titled "Avatar" becomes the highest grossing movie of all time, and people wanted to have the same technology that they saw on the big-screen in their homes.

This sudden love for 3D movies put television makers like Sony, Toshiba, and Samsung on watch. Within months, hundreds of new televisions were flooding the market with a new selling point: 3D capability. While you still need to wear somewhat dorky-looking 3D glasses, at least you will be in the privacy of your own home.

So, is 3D TV all that it is cracked up to be? This question seems to depend on who you are, and more importantly, how old you are. Younger people who have seen technology transform before their eyes seem to love having 3D movies and sports available to them day and night. For older generations, 3D is enjoyable to watch but is something they would rather experience occasionally than full-time.

For people who only want to watch their favorite movie or sports in 3D, there is good news. You can watch a 3D TV just like any other ordinary TV when it is not in 3D mode, but with the push of a simple button you can also enjoy the 3D movie theater experience in your own home.

All signs are pointing to 3D technology not disappearing soon, in fact it is likely expand. Playing 3D video games or viewing your own 3D photographs on your 3D compatible television is believed to be just around the corner. 3D compatible cell phones and laptops will also be shipping to homes by the end of 2011.

If you recently bought a Plasma or LED television that is not 3D compatible, you are unfortunately out of luck. A television must be labeled "3D compatible" to enjoy this new technology. If you are now shopping for a new TV, almost all are being manufactured with a 3D mode.

For people who want to enjoy 3D but hate having to wear 3D glasses to view 3D images, there is good news. Sony and Samsung have developed prototype 3D televisions, which can be viewed in 3D without glasses. This could bring 3D television viewing to an entirely new level. Do not count on seeing these TVs in store anytime soon though, because it may be two to three years before they are available to consumers.
