NLP is a technology for modeling the genius of high performers. In the 30 years since it's birth in Santa Cruz, it has become a key technology in business, management, marketing, and athletics. Grinder and Bandler published many influential NLP books in the 1970's and each continued to develop nlp in different directions since that time. In recent years, other influential contributers such as Judith Delozier and Robert Dilts, have influenced and impacted the field of NLP. Many self improvement authors have taken these tools to the masses. Some ideas about resuppositions from linguist George Lakoff influenced the field of Nlp early on, though he was never a part of the field. Lakoff's ideas of "framing" have made deep inroads into progressive political discourse.
