The Big Idea Book: Five hundred new ideas to change the world in ways big and small

Idea A Day was founded in 2000 by David Owen, Becky Clarke, Rupert Kaye and Chas Bayfield. Respectively, they work in the music business, advertising, education and advertising [again]. Between them they all have a lot of ideas.

The aforementioned are all at pains to point out that they did not write the majority of the entries in this book. The ideas were submitted by individuals from around the world. They were gratefully received and are published here with further thanks.
