Okay, since you didn't include a

, I'll assume you're serious:
In a nutshell,
Oprah is the today's most famous and celebrated of American talk show hosts and one of the richest women in the world. On her talk shows, she occasionally surprises her audiences by giving them ALL gifts, everything from cosmetic bags to (I swear to God) cars. Her book club is arguably as popular in the US for book selections and recommendations as the New York Times Bestseller List (that's why we brought her up). She also publishes a magazine... something else that could be a viable e-book product, once large-size e-readers go color.
(BTW, by my first sentence, I wasn't suggesting that everyone in the world should know Oprah! Just messing with you!)
