The First Industrial Revolution, which ended in the early to mid 1800s, was punctuated by a slowdown in macroinventions before the Second Industrial Revolution in 1870 . Though a number of its characteristic events can be traced to earlier innovations in manufacturing, such as the establishment of a machine tool industry, the development of methods for manufacturing interchangeable parts and the invention of the Bessemer Process to produce steel, the Second Industrial Revolution is generally dated between 1870 and 1914 (the start of World War I). </P> <P> Advancements in manufacturing and production technology enabled the widespread adoption of preexisting technological systems such as telegraph and railroad networks, gas and water supply, and sewage systems, which had earlier been concentrated to a few select cities . The enormous expansion of rail and telegraph lines after 1870 allowed unprecedented movement of people and ideas, which culminated in a new wave of globalization . In the same time period, new technological systems were introduced, most significantly electrical power and telephones . The Second Industrial Revolution continued into the 20th century with early factory electrification and the production line, and ended at the start of World War I . </P>
