"Commercial software companies face many challenges in growing their business in today's fast-moving and competitive industry environment. Recently many people have proposed the use of an open-source development model as one possible way to address those challenges. This document investigates the business of commercial open-source software, including why a company might adopt an open-source model, how open-source licensing works, what business models might be usable for commercial open-source products, what special considerations apply to commercial products released as open source, and how various objections relating to open source might be answered."
