A.A. Milne's beloved character Winnie-the-Pooh first appeared in book form on Oct. 14, 1926, and the teddy bear with a taste for honey has been delighting generations of readers ever since. Charles Osgood traced the origins and longevity of Winnie and his friends (including Eeyore, Piglet and Christopher Robin) in this 2012 "Sunday Morning" Almanac.
