International Museum Day has been celebrated worldwide since 1977. ICOM (International Council of Museums) is responsible for determining a theme each year.
The event offers museums and their professionals the opportunity to reach out to the public and society and make them aware of the changes that museums are developing, since as ICOM itself says, they are "an institution in the service of society and its development".
Evidence of the success of this celebration are the figures that ICOM provided last year, where 90% of Spanish museums participated in IMD 2011. The motto proposed this year by ICOM is: "Museums in a changing world. New challenges, new inspirations" they recognize that institutions adopt an interpretive approach and move in an increasingly fluid environment.
Each one strives to achieve objectives and attract new visitors, but the common need to prosper unites all these museums, large or small.
In this way, IMD 2012 focuses not only on the growth of museums and the construction of their future, but also on other issues such as climate change and new electronic media.
