First newspaper using central electricityIn 1882, the first newspaper plant to make use of the newly available electrical power provided by the Edison Illuminating Company was the New York Times. The building had previous been wired, with light fixtures and electric meters installed and inspected by an expert from the Board of Underwriters. There were 27 lamps installed in the editorial room and 25 lamps in the counting room. Next day, in the newspaper's own article, the workers were said to be unanimously in favour of the light provided by the carbon-filament lamps as being brighter and steadier than the gas lighting it replaced. There was no nauseous smell, and the lamps were very convenient to light by simply turning a thumbscrew. Additional lights were added later for the composing and press rooms.«[Image: Exterior of New York Times building, c. 1874.] |
