because in cinema they use polarized plastic glasses, which are very cheap to produce - the light polarization technique uses 2 beamers.. there are some professional TVs that can do it as well, but that technique for TVs has some draw backs like halfed vertical or horizontal resolution
first gen 3D TVs all use shutterglasses - these glasses synchronize with the TV and alternately darken (at 120Hz) one glass (they have LCDs in each glass) depending on which eye-picture the TV outputs at that time, which is why these glasses are way more expensive
