The concept that certain contemporary works merge already known art forms to inaugurate a new type. If the resulting art form gains currency and acquires a name, it becomes a new medium and is no longer intermedia. For works that employ several distinct art forms, such as sculpture and music, see "multimedia works." To indicate that works are composed of a variety of materials, see "mixed media."
