rise of modern machines

One example of how technology made working life easier in the early 1900's was the way factories became much more efficient with the invention of electricty. In 1909 there was a boom in triangle factories, over 500 were in operation in New York city alone. triangle factories were usually very loud and the working evironments dim and dinghy but work was done quickly. Every thing from th sewing machines to the telephone ran off of electricty.
