"The great white way"

Does anyone know how the saying "the great white way" (as in broadway) started or its origin. Ive been looking all over and there is no place of origin menotioned anyware. I was thinking it probly has to do with racism... does anyone one know?

Not racism. It's about the lights on the fronts of theaters.

Yes, and in particular, the phrase refers to the theatre district in NYC. The "Great White Way" refers to Broadway between the low 40s to the low 50s.
