"In 1880, Brush Electric Light and Power Co. installed the first electric street lighting on Broadway from 14th Street to 26th Street. Madison Square was also illuminated. The first public use of electricity is said to have happened just 2 years earlier in Paris".
First episode in which the title is not spoken in dialogue during the episode itself (which may befit the title "Irresistible Change"). Additionally, the title of the following episode, "Tucked Up in Newport", is spoken in this episode and not in Ep. 8 itself.
This episode depicts a historical moment - when Thomas A. Edison turned on the newly installed electric lights in the New York Times building on Park Row on 4 September 1882.
