The biotechnology industry is comprised of all organizations involved in the development, manufacturing, or marketing of products that are based on bio-molecular research. The industry is closely aligned with the research and development aspect of the pharmaceuticals and agriculture industries, which generate the bulk of industry revenues. In North Carolina, the biotechnology industry has grown up around the Research Triangle Park (RTP), an office park located between Durham and Raleigh that was built in the late 1950s. The National Institute of Environmental Health Sciences, GlaxoSmithKline, Monsanto, Novartis, and other large pharmaceutical and biotechnology companies have had a presence at RTP. Nearby universities and an extensive community college system have fed the industries need for highly skilled scientists and business representatives.
