The first glasses free 3D television was demonstrated in 1929 by John Logie Baird, the inventor of the worlds first fully operating television system. Although his original television went into commercial service, the 3D television never made it to homes.
There are two technologies in use with 3D television. Active 3D requires glasses that have batteries while passive models do not. Crosstalk in active glasses has been a problem but it depends on the make of glasses and television. For passive 3D, look at Sony, Visio, Toshibe or LG.

You don't need any! Just slide the 3D depth slider on the top screen and you get glasses free 3D!
Glasses free 3D is at an experimental stage at present. The few examples are expensive and not impressive quality either. It will improve and the costs will come down in the future but if you are considering 3D television, don't wait for glasses free systems - it will be a long wait for you.
Toshiba has already launched glasses free 3D TV. But it has its limitations that only 11 people can watch 3D at a time and it is not as effective as other present 3D TVs

The first use of 3D glasses was in 1922 for the movie "Power of Love".
Yes. Toshiba makes models that are autostereoscopic (glasses-free) however these models are very very expensive.
LG Cinema 3D is probably the best one to go for if you want a theater-like 3D experience. LG Cinema 3D series use the same technology as the movie theater 3D screens (as opposed to shutter glasses technology in other 3D tvs). LG Cinema 3D uses lightweight, battery free 3D glasses that give you flicker free and crosstalk free images. You can actually use 3D glasses from movie theaters with LG Cinema 3D (you can't with other 3D tvs).
Battery free glasses for 3D are better if they are being used with passive 3D televisions. LG only have passive 3D television so the battery free glasses work with them. The other premium brands such as Samsung, Sony etc all use active 3D and their glasses are battery powered. The active glasses are far better for use with active televisions because the battery free glasses won't work with them. Previous criticisms of active glasses were weight and battery life. With the weight below one ounce and battery life of over 100 hours, neither of these are issues any more.
he invented 3d glasses to see things that aren't there
