adidas, Puma, Nike: Once upon a time in Sports

Hi all,
I have been talking about adidas, Puma and Nike on this blog for a couple of months. But how well do you know the history of these sports brands? Nike is obviously younger than its major competitors, but did you know that Nike was called different at the beginning? Do you know how adidas and Puma are historically linked? Not too familiar with all of this? here is a chronological catch up.
