The International Council of Museums (ICOM) created International Museum Day in 1977. The organisation chooses a different theme for the day and coordinates every year. Some of the themes include globalisation, indigenous peoples, brigding culture gaps and caring for the environment. Every year since 1977, all of the museums in the world are invited to participate in this day to promote the role of museums around in the world, by organising enjoyable and free activities around the year’s theme. International Museum Day has become steadily more popular since its creation, with International Museum Day 2009 being participated in by 20,000 museums in over 90 countries. In 2012, the number of participating museums had jumped to 30,000 in 129 countries.
