Tungsten Territory (Broadway)

Broadway’s bright lights gave it the nickname “Tungsten Territory.” Broadway columnist Walter Winchell (1897-1972) used “Tungsten Territory” in 1927 and “Tungsten Belt” in 1930.
 
Other nicknames for Broadway and its bright lights include “Bulb Belt,” “Great Bright Way,” “Great White Way,” “Incandescent District,”  “Lane of Lights and Laughter,” “Mazda Lane,” “Street of the Midnight Sun” and “White Light Belt.”
