Abstract
We review the impressive progress on light self-localisation into spatial optical solitons in nematic liquid crystals. We summarise the basic physics and models, outlining the main properties of nematicons and providing an overview of the most significant experimental achievements in undoped, planar, twisted and chiral nematic liquid crystals.
