OpenCourseWare was proposed by MIT in 2001 and launched its web site with five hundred courses in 2003. MIT have paid much effort not only for moving forward their own activity but also for promoting OCW to many institutions all over the world since 2004. Global OCW have grown rapidly under the OpenCourseWare Consortium who has been established as a non-profit organization since 2008 and nowadays more than two hundred and eighty organizations joined the consortium from all over the world. Currently some new challenges have been started in various countries to advance OCW. One of them is creating learners community to share opinions and QA among users who are learning same course. The other is to give certificates to learners who completed the course to admire their learning achievement. In near future Open Education might be the global content infrastructure for life-long education.
