It's a big week for Nike co-founder and chairman Phil Knight, whose memoir Shoe Dog releases tomorrow, April 26.

Since he's got a book to promote, Knight's been in the public eye just a tiny bit more than usual, appearing onĀ CBS Sunday Morning over the weekend to discuss the history of the world's most powerful sportswear brand.

In the interview, Knight talks about sweatshop controversies that harmed the company's public image, sneaker violence, and the early days of his company.

The biggest revelation Knight makes in the clip is his plan to give away most of his $26 billion fortune.
