ソーシャルビジネスとしてのオープンソース

The document discusses open innovation versus closed innovation. Open innovation is a paradigm that assumes that firms can and should use external ideas as well as internal ideas, and internal and external paths to market, as the firms look to advance their technology. It stands in contrast to the traditional closed innovation model where internal research and development departments of firms attempt to develop their own ideas. The document also provides an overview of the history and development of the Linux kernel from its origins to its current role as a widely used open source operating system.
