Nikon have VR (vibration reduction), Olympus have it built in camera.

Sigma call it OS (optical stabilisation), Panasonic/Leica call is MegaOIS (optical image stabilisation).
Pentax have sensor shift in camera and call it SR (shake reduction).
Sony have sensor shift in camera and call it Super SteadyShot.
Just to confuse you even more, Canon actually utilise 3 different levels of image Stabiliser. The 'consumer' lenses - ie the non 'L' lenses have the 1st generation of image stabiliser. It is slower and noisier than those in the 'L' lenses and you only have the option of turning it on or off. Both the 28-135IS and 70-300IS use this.
When you pay more money out and go to the 'L' lenses, you progress to a better level of IS - you get to decide if you want both horizontal & vertical shake to be reduced (mode 1), or only a single direction (mode 2). Mode 2 allows you to pan/follow a moving subject and still reduce the shake. The 100-400IS falls into this category.
The last version is only found in their 'supertelephoto' (300/2.8 and 400/2.8, 500/4, 600/4) lenses and adds a sensor to detect if the lens is being used on a tripod and adjusts the IS accordingly. In the other two versions it's generally recommended that you turn IS off when using the lens on a tripod otherwise it may actually induce shake!
IS is very useful for shooting while hand holding the camera/lens and for using when resting on hide/window ledges.

Keep and eye open for more OS lenses from Sigma, especially in the longer focal lengths!
