Behind the Polaroid
A (relatively) new book by Christopher Bonanos explores the life and inventions of Polaroid founder Edwin Land.
On the companion site to the book, Bonanos, an editor at New York Magazine, writes:
Instant: The Story of Polaroid is a book about a very unusual company. In the 1960s and 1970s, Polaroid was what Apple is today: the coolest technology company on earth, the one with irresistible products, the one whose stock kept climbing way past the point of logic. In its heyday, Polaroid was an absolute innovation machine—a scientific think tank that periodically kicked out a fantastically profitable, covetable product. In fact, the late Steve Jobs expressly said that he modeled his company to a great extent after Polaroid.
Launching a new brand is expensive. Far easier, these days: Bring back (or polish up) an old one.
