I recommend that you pick up a copy of The Code Book; it's an informative and enjoyable read. To be more specific, Applied Cryptography lists Differential Cryptanalysis as being public found in 1990. So, that puts the IBM researchers / NSA only 14 years ahead of the rest of the world. Good thing they decided to protect against the attack rather than weaken DES to it.
