I recently read Mac B Cracks the Code (http://www.amazon.com/exec/obidos/ASIN/1338594230/donhosek ) to my kids and there's a history of Nintendo as part of the story. They began as a playing card company in 1889, entered into businesses like making instant rice and offering taxi service before getting into toys in 1969 and releasing their first video game in 1973. They've got a long history of reinvention.
