Chicken House has launched a competition to discover "the next big story idea" that will "challenge convention on how great ideas become stories today".   The judges of the Big Idea are Chicken House founder and publisher Barry Cunningham; Tess Daly, TV broadcaster; literary agent Neil Blair, who represents J K Rowling; Debra Hayward, film producer; Sonia Friedman, theatre producer; and Philip Ardagh, children's author and critic. They will choose six winning ideas, with the creators winning £1,000 each and the chance to see their ideas come to life. Chicken House will offer the overall winner a publishing contract for the development of his or her idea by an established author. "The Big Idea is an exciting new way to bring new children's stories to life by going to the heart of every one of them: the big idea at their core," explained Blair, while Daly added: "All the best children's books come from a great idea, and a great idea can come from anywhere! I've joined forces with the Big Idea to celebrate Britain's talent for storytelling and creativity. There are so many people who have a seed of an idea for a book, film or TV programme but don't know what to do with it, so this is their chance to get support from the best. I love sharing and making up my own stories with my children - so I can't wait to help uncover the next big story idea to be loved by adults and children alike." The overall winner's publishing contract will be in line with industry standards, with a shared royalty on every copy sold. The six winners could also see their idea work across a variety of media platforms, including film, TV, gaming, websites, apps and stage, with a commensurate royalty share. Creative writing ability isn't a requirement - entrants simply need to outline their ideas in up to 750 words. There are ideas and guidelines at www.thebigideacompetition.co.uk. The competition opened, Monday 7 July, and closes 2 September. The winning ideas will be announced in early November.
