Back in 1974, adidas began associating itself with the “Impossible is Nothing” slogan, which was an extract from a Muhammad Ali quote.

“Impossible is just a big word thrown around by small men who find it easier to live in the world they’ve been given than to explore the power they have to change it. Impossible is not a fact. It’s an opinion. Impossible is not a declaration. It’s a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”
