PolaroidA 3-year-old's question became Polaroid.

A Jewish inventor's three-year-old asked him one question. It became a billion-dollar company. Santa Fe, 1943.

Edwin Land snapped his daughter's photo. Back then, film took days at a lab. So she asked why she couldn't see it now.

Land went for a walk. Within an hour, he'd pictured a camera that develops its own photo. It took three years of chemistry.

Then, in 1947: a finished print in one minute. The first Polaroid cameras sold out on day one. By the late seventies, Polaroid sold over a billion dollars a year.

And Steve Jobs called Land one of his heroes. "A camera that would be, oh, like the telephone, something that you use all day long."
