The second industrial revolution started around 1870 and ended around 1930. It was characterized by ongoing mechanization because of the introduction of the assembly line, the replacement of iron by steel and the development of the chemical industry. Furthermore coal and water were replaced by oil and electricity and the internal combustion engine was developed. Whereas the first industrial revolution was started through (chance) inventions by amateurs, companies invested a lot of money in professional research during the second revolution, looking for new products and production methods. In search of finances small companies merged into large scale enterprises which were headed by professional managers and shares were put on the market. These developments caused the transition from the traditional family business to Limited Liability companies and multinationals.
The United States (U.S.) and Germany led the way in the Second Industrial Revolution. In the U.S. there were early experiments with the assembly line system, especially in the automotive industry. In addition, the country was a leader in the production of steel and oil. In Germany the electricity industry and the chemical industry flourished. The firms AEG and Siemens were electricity giants. German chemical companies such as AGFA and BASF had a leading share in the production of synthetic dyes, photographic and plastic products (around 1900 they controlled some 90% of the worldwide market). In the wake of these two industrial powers (which soon surpassed Britain) France, Japan and Russia followed. After the Second Industrial Revolution ​​more and more countries, on more continents, experienced a more or less modest industrial development. In some cases, the industrialization was taken in hand by the state, often with coarse coercion - such as the five-year plans in the Soviet Union.
After the roaring twenties the revolution ended with the stock exchange crash of 1929. The consequences were disastrous culminating in the Second World War.

3. The third industrial revolution
The third industrial revolution started around 1940 and is nearing its end. The United States and Japan played a leading role in the development of computers. During the Second World War great efforts were made to apply computer technology to military purposes. After the war the American space program increased the number of applications. Japan specialized in the use of computers for industrial purposes such as the robot.
From 1970 the third industrial revolution continued to Europe. The third industrial revolution was mainly a result of a massive development of microelectronics: electronic calculators, digital watches and counters, the compact disc, the barcode etc.
The acceleration phase of the third industrial revolution started around 1980 with the advent of the microprocessor. The development of the microprocessor is also the basis of the evolution and breakthrough of computing. This had an impact in
many areas: for calculation, word processing, drawing and graphic design, regulating and controlling machines, simulating processes, capturing and processing information, monetary transactions and telecommunications. The communication phase grows enormously at the beginning of the new millennium: the digital revolution. According to many analysts now a new era has emerged: that of the information or service economy. Here the acquisition and channeling of information has become more important than pure production.
By now computer and communication technology take up an irreplaceable role in all parts of the world. More countries depend on the service sector and less on agriculture and industry.

Effects of three industrial revolutions
The first (and second revolution) transformed an agricultural society into an industrial society where mechanization (finally) relieved man of physical labor. The craft industry could not compete with the factories that put products of the same or even better quality on the market at a lower price. The result was that many small businesses went bankrupt and the former workers went to work in the factories. The effects of industrialization were seen in the process of rapid urbanization of formerly relatively small villages and towns where the new plants came. These turned into dirty and unhealthy industrial cities. Still people from the country were forced to go and work there. Because of this a new social class emerged: the workers, or the industrial proletariat. They lived in overcrowded slums in poor housing with little sanitation. The average life expectancy was low, and infant mortality high. The elite accepted the filth of the factories as the inevitable price for their success. The chimneys were symbols of economic power, but also of social inequality. You see this social inequality appear after each revolution. The gap between the bottom and the top of society becomes very large. Eventually there are inevitable responses that decrease this gap. It could be argued that the Industrial revolutions have created the conditions for a society with little or no poverty.
The third revolution transformed an industrial society into a service society. Where mechanization man relieved of physical labor, the computer relieved him of mental labor. This revolution made lower positions in industry more and more obsolete and caused the emergence of entirely new roles in the service sector.
