KEEP CALM AND CARRY ON - The British government printed over 2.5 million of these posters at the beginning of the second world war. They were never distributed and mostly destroyed. One copy was found by a bookseller in a box in 2000 framed, displayed and copied. It has become a "meme" appearing on posters , mugs, and paraphernalia, and has been adapted to suit many different scenarios. eg "KEEP CALM AND PRESS CTRL-ALT-DEL" OR "I AM A RUSSIAN AND I CANNOT KEEP CALM". (meme (/ˈmm/meem)[1] is "an idea, behavior, or style that spreads from person to person within a culture."[2] A meme acts as a unit for carrying cultural ideas, symbols, or practices that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena. Supporters of the concept regard memes as cultural analogues to genes in that they self-replicate, mutate, and respond to selective pressures.[3
