Yes Cinema's use polarised as would people at a tradeshow viewing 3D from a 3D Projector.
For 3DTVs
RealDs "technology" in "Shutter" glasses which are like Nvidias and sync/block out the eye thats not meant to see the frame rapidly to create the 3D illusion.
You also get no real discolour issues like with red/blue.
"Of course, the hidden cost in many of the upcoming 3D TVs we'll be seeing at CES lies with these battery-powered active shutter glasses. I haven't heard any prices from the big TV manufacturers yet, but in the past I've heard figures that top out at about $100 a pop. So if you've got a family of five that wants to watch a movie in 3D on your new Vizio, well ... you do the math. (For the record, Vizio hasn't yet announced how much its active-shutter 3D glasses will cost.)
The (far) cheaper alternative to active-shutter 3D glasses are "passive" polarized 3D glasses, similar to the disposable glasses you get in most 3D movie theaters. The downsides to using polarized glasses on a 3D TV? The 3D image might not be as good (image brightness could suffer, and there's a better chance that the image meant for one eye might "bleed" into the other eye, also known as "crosstalk"), and the 3D TV in question typically would need a screen with a polarized coating, which might boost the price of the set."

Sensio is widely being used inc SKY etc?
More News & Panasonic RealD not Xpand?
Yes Panasonic Also Confirmed / RealD
Sensio & THX
Ah yes, I remember now, Cinemas (and in particular IMAX) have a "special" silver screen to compensate for the lack of brightness caused by using polarised lenses.
Sounds like polarised glasses = cheap but corresponding TVs would cost more, and vice versa for these shutter glasses.
Your quote highlights my concern really, I don't think people mind shelling out a bit more for a TV as it should last a long time. Whereas glasses, are likely to break/need replacing/need multiple sets etc which will be expensive. People moan about having to buy £35 controllers and their corresponding batteries/charging, I suspect shutter glasses will cost more.
Also one final thing I was thinking about is, anyone watching you play a game is going to have a really crappy viewing experience unless they wear glasses too. I can think of many a time where 4 of us are sitting in a room playing 2 player games, taking turns, whilst the other 2 watch/chat etc.
