Many years ago, there was the debate over Betamax and VHS in bringing videos into your home.
VHS won that battle, despite being the poorer technology.
More recently, we have seen the battle between Blu-rays and HD DVD's.
This time, the more expensive, but better quality technology won.
In our battle with ever advancing technology, we have always pushed the boundaries.
The most recent televisual technology to emerge in recent years has been that of 3D.
This has been highlighted in particular by movies like Avatar, which was in part made to specifically showcase the technology of 3D to the masses.
Shortly there followed films and movies being released in 3D format and this has resulted in 3D technology being the next must have in our homes in order to keep up with the Joneses.
There are two types of 3D TV available.
Those which require active glasses and those which require passive glasses.
The active glasses give a sharper picture, and cope better with faster moving pictures.
However, anecdotally they are more likely to result in headaches, especially when the viewer is tired, and they are also generally more expensive than passive 3D.
The passive 3D TV will still give you a 3D viewing experience, and of course, is less likely to result in the aforementioned headaches.
The price of the technology is always coming down as technology continues to advance, so is it time to invest in one of these television sets if you don't have one already.
Well, the biggest argument so far against has been the lack of content, but this is changing.
Some sports events and concerts are now being broadcast in 3D (it really is something to see all the sand flying out of the sand trap towards you as a bunker shot is played in golf, or to have a tennis ball or baseball coming at you, or perhaps feel the thundering tackle in a football game).
But increasingly, more and more movies are being made in 3D off the back of the success of Avatar.
Some older films have also been converted to 3D, such as Titanic, they will lack some of the crispness of Avatar though, as this was made specifically for 3D.
One of the other more recent developments has been 3D gaming resulting in an immersive experience that sees you driving a car in 3D, as if you were at the race track, or battling it out in a first person shooting game (maybe too scary for some).
It is definitely worth the investment if you really enjoy the 3D experience (either in the cinema or when gaming).
Otherwise, you could wait and get one when your current TV breaks and the prices have come down even more.
