m3c Multimedia Centres Network of Slovenia is rooted in a non-formal network, originally called the 'Cultural Information Backbone', which was formed in the second half of the 1990s. The project's aim was to connect organisations working with digital and information technologies and artistic production. Following funding from the Ministry of Culture and the former Ministry of Information Society, as well as from the European Regional Development Fund (ERDF), the infrastructure of the network was extended to cover all Slovene regions.

The m3c Multimedia Centres Network of Slovenia aims to network with existing and emerging intermedia initiatives in all Slovene regions and to encourage international co-operation.
