A given. Aside from raising America’s spirits throughout the ‘30s and ‘40s, he also showed the world that its national sports heroes didn’t have to be white.
Also a given, but seriously, think what music would be without Motown. No "My Girl." No "Please Mr. Postman." No "Ain’t No Mountain High Enough." No Miracles, no Jackson Five, no Supremes, no Stevie Wonder. In effect, karaoke would be lifeless, rom-com montages would contain zero to no dancing, and high school football teams would have nothing to sing in hilarious moments of locker room bonding.
