'Brochures' covers a multitude of sins, along with probably around half of our workload.

A 'brochure' could be a leaflet in all but name - a little two-fold A4 that tells somebody how to go about insuring their mobile. Or it could be a brand manual, probably accompanied these days by a CD-ROM, web-site or both, equipping a major multinational for metamorphosis into a global brand. Most often, it's simply the easiest and most precisely targeted way to take a particular message to a specific audience.
