Hawking states in A Brief History of Time that an editor advised him to use as few mathematical equations as possible. because the book would not sell well if it had a lot of equations in it. As a result, Hawking decided to use only one equation, the famous E=mc2.
The book contains several diagrams to help make Hawking's explanations of complicated subjects clearer.
The first edition included an introduction by Carl Sagan. However, because the copyright to the introduction was held by Sagan himself rather than Hawking or the publisher, the introduction was missing from later editions.
In 1996 an expanded and updated edition was published, the hardback edition of which contained full color illustrations and photographs.
In 2005 A Briefer History of Time, co-authored by Stephen Hawking and Leonard Mlodinow, appeared. A Briefer History of Time is an abridged version of A Brief History of Time, updated to reflect advances in scientific understanding since the book's first publication.
An American documentary called A Brief History of Time was released in 1991. The documentary was directed by Errol Morris and featured music by Philip Glass.
