TPR Storytelling is unusual in that it is a grassroots movement among language teachers. After being developed by Blaine Ray in the 1990s, the method has gained popular appeal with language teachers who claim that they can reach more students and get better results than they could with previous methods. It is enjoying increasing attention from publishers and academic institutions. A number of practitioners publish their own materials and teaching manuals, and training in TPR Storytelling is generally offered at workshops by existing TPRS teachers rather than at teacher training college.
