Links on the history of formula companies

a friend and i were discussing BFing, and she was wondering where the whole ignorant notions of, "BF is gross! my boobs are for me and my man, and nobody else!" :

i was telling her about some really great reading i had done on the deceptive info formula companies used to use to scare women into ff....well, now i can't remember where these great links are! if you have some good ones (i'm interested in the more historic/educational side of it) please post them!

tia!
