The term fanzine comes from the combination of the words 'fan' and 'magazine'. It is a publication created by enthusiasts of particular forms of art and culture. A fanzine is an independent publication that anyone can produce and is not susceptible to censorship or the need to adhere to the commercial criteria of a publishing company.
