The Medium is the Massage: An Inventory of Effects
is a book co-created by media analyst Marshall McLuhan and graphic designer Quentin Fiore, and coordinated by Jerome Agel. It was published by Bantam books in 1967 and became a bestseller and a cult classic. The book itself is 160 pages in length and composed in an experimental, collage style with text superimposed on visual elements and vice versa. Some pages are printed backwards and are meant to be read in a mirror (see mirror writing). Some are intentionally left blank. Most contain photographs and images both modern and historic, juxtaposed in startling ways. The book was intended to make McLuhan’s philosophy of media and communication, considered by some incomprehensible and esoteric, more accessible to a wider readership through the use of visual metaphor and sparse text.
