San Serriffe

San Serriffe is a fictional island nation created for April Fools' Day 1977, by Britain's "Guardian" newspaper. It was featured in a seven-page hoax supplement, published in the style of contemporary reviews of foreign countries, commemorating the tenth anniversary of the island's independence, complete with themed advertisements from major companies. The supplement provided an elaborate description of the nation as a tourist destination and developing economy, but most of its place names and characters were puns and plays on words relating to printing (such as "sans-serif" and names of common fonts). The original idea was to place the island in the Atlantic Ocean near Tenerife, but because of the ground collision of two Boeing 747s there a few days before publication it was moved to the Indian Ocean, near the Seychelles Islands. Because of this late move the authors made San Serriffe a moving island - a combination of coastal erosion on its west side and deposition on the east cause it to move towards Sri Lanka, with which it will eventually collide, at about 1.4 km/year.
San Serriffe was one of the most famous and successful hoaxes of recent decades; it has become part of the common cultural heritage of literary humour, and a secondary body of literature has been derived from it. The nation was reused for similar hoaxes in 1978, 1980 and 1999. In April 2009 the geography, history and culture of San Serriffe featured heavily in the paper's cryptic crossword.
Background.
The idea for the hoax came from the "Guardian"′s Special Reports Manager Philip Davies. In a 2007 interview he said "The "Financial Times" was always doing special reports on little countries I'd never heard of. I was thinking about April Fool's Day 1977 and I thought, why don't we just make a country up?" Special Reports editor Stuart St Clair Legge suggested the name San Serriffe. Geoffrey Taylor designed the semicolon-shaped map of the island, based on a shrunken version of New Zealand. 
Initially, the supplement featuring the fictitious archipelago was to be a single page. However, the newspaper realized that a larger, more in-depth review would generate greater revenue by running themed advertising alongside the text. These included a request for submissions to a photography competition sponsored by Kodak: "If you've got a photograph of San Serriffe, Kodak would like to see it."
Reception.
In an era before the widespread use of desktop publishing and word processing software, much of the terminology was little-known, the jokes were easily missed, and many readers were fooled. Despite this, many others recognised the joke and became part of it. "The Guardian" received hundreds of letters from readers describing memorable holidays to the islands. It also received a letter from the "San Serriffe Liberation Front" critical of the pro-government slant to the supplement.
Editor Peter Preston received letters of complaint from airlines and travel agents due to the disruption caused by customers who refused to believe the islands did not exist.
Legacy.
A large body of secondary work about San Serriffe has been written since 1977. A Friends of San Serriffe club was established, with its "life president" writing annual April Fools' Day letters to the paper. Bird & Bull Press published several books about esoteric subjects relating to the country, including "Booksellers of San Serriffe", "First Fine Silver Coinage of the Republic of San Serriffe" and "The Most Inferior Execution Known Since the Dawn of the Art of Marbling Collected by the Author During a Five Year Expedition to the Republic of San Serriffe".
Donald Knuth offers a reward to anyone finding a mistake in one of his publications, and from October 2008 onwards this has been in the form of a "certificate of deposit" from the fictitious "Bank of San Serriffe".
