Abstract. Is OSS undergoing a transformation to a more commercially viable form? We have performed a survey to investigate the adoption of OSS in the Norwegian software industry. The survey was based on an extensive screening of software companies, with more than 700 responses. Analysis shows that close to 50 % of the software industry integrate OSS components into vertical solutions serving all major business sectors. In addition, more than 30 % of the companies using OSS components have over 40 % of their income from OSS related services or software. The adoption of OSS in the software industry may be a precursor of the OSS adoption in other business sectors.
