Falling Whistles
Falling Whistles sells whistles for $34 to $104 to raise money for education, advocacy, and the rehabilitation of war-affected people in Congo. The organization got its name from a journal written by its founder, sharing his experiences during a trip to eastern Congo in 2008. During that trip, Falling Whistles' founder met a group of five former child soldiers who told him that some children who were too young to carry weapons were sent into battle armed only with whistles. By wearing whistles, the campaign aims to use this weapon as a tool of protest and to raise awareness of the situation in Congo. As of September 2010, $500,000 has been raised.
Edmond Hoyle
By 1741, Hoyle began to tutor members of high society at the game of whist, selling his students a copy of his manuscript notes. Hoyle expanded the manuscript and published "A Short Treatise on the Game of Whist" in 1742, selling it for the high price of one guinea.
When the book quickly sold out, rather than publish a new edition, Hoyle sold the rights to "Whist" to bookseller Francis Cogan for 100 guineas, an enormous sum for a small pamphlet. Before Cogan was able to publish a second edition, two printers pirated the work, giving the author as "A Gentleman" rather than Hoyle. The printers disguised their identities by publishing under false names, one as Webster, the other as Webb. Cogan published second and third editions of "Whist" and two months later, obtained an injunction against the pirates which he announced in a fourth edition (all 1743). To distinguish the genuine editions from the piracies, Cogan paid Hoyle twopence per copy to autograph the genuine works. The piracies were profitable to Hoyle, though a disaster for Cogan who was forced to lower the price of the book to match the pirates and to pay for Hoyle's signature.
