This document discusses how free and open source software enables business innovation. It notes that 85% of companies use open source software and the Linux ecosystem is projected to become a $50 billion industry by 2011. Free software allows for freedom to use, study, share, and improve software. While some claim it is non-commercial, many businesses earn revenue through services, support, training and more without selling proprietary licenses. Free software fosters both competition and cooperation between businesses. Policymakers should support free software to help new businesses and free up public sector software.
