The steamboat changed the way of living of people and greatly affected the Industrial Revolution. It became the main mode for the transportation of goods and products in the 1800s. The efficiency of doing so would have been impossible without the steamboat. It increased the capabilities of commercial trading thus, leading to the creation of new towns and the stimulation of the economy. Steamboats increased the dependency to manufactured products because the speed of transportation became faster than the standard speed. Steamboats played a vital role in the supply and demand chain.
