BRDIS expands NSF's coverage of business R&D and innovation activities. It is the successor to IRIS (Industrial Research and Development Information System). IRIS links an online interface to a historical database with more than 2,500 statistical tables. These tables, drawn from the results of the annual Survey of Industrial Research and Development (SIRD), contain all the industrial R&D data published by NSF from 1953-2007. IRIS data prior to 1999 are based on Standard Industrial Classification (SIC) and pre-SIC codes. Beginning with the 1999 survey, estimates are based on the North American Industrial Classification System (NAICS). Successor is the Annual Business Survey.
