This is not a technique I've ever employed, so I don't really know specifics (I bet Wikipedia does) but I think technically the term means a sprite that always faces the player (versus the technique of stitching together flat polygons... games deploy both) ...I guess I will look it up later.
Billboards are actually more interesting / closer in metaphor when they are generated on the fly as seen from far distances / low LOD. With trees on the far horizon for example you can render a hundred branches to a flat sprite then update rendering again when the view angle or LOD changes.
