Such internal improvements not only spread goods, they spread information. The transportation revolution was followed by a communications revolution. The telegraph redefined the limits of human communication. By 1843 Samuel Morse had persuaded Congress to fund a forty-mile telegraph line stretching from Washington, D.C., to Baltimore. Within a few short years, during the Mexican-American War, telegraph lines carried news of battlefield events to eastern newspapers within days. This contrasts starkly with the War of 1812, when the Battle of New Orleans took place nearly two full weeks after Britain and the United States had signed a peace treaty.

Slave labor helped fuel the market revolution. By 1832, textile companies made up 88 out of 106 American corporations valued at over $100,000.14 These textile mills, worked by free labor, nevertheless depended on southern cotton, and the vast new market economy spurred the expansion of the plantation South.
While the Irish settled mostly in coastal cities, most German immigrants used American ports and cities as temporary waypoints before settling in the rural countryside. Over 1.5 million immigrants from the various German states arrived in the United States during the antebellum era. Although some southern Germans fled declining agricultural conditions and repercussions of the failed revolutions of 1848, many Germans simply sought steadier economic opportunity. German immigrants tended to travel as families and carried with them skills and capital that enabled them to enter middle-class trades. Germans migrated to the Old Northwest to farm in rural areas and practiced trades in growing communities such as St. Louis, Cincinnati, and Milwaukee, three cities that formed what came to be called the German Triangle.
Friedrich Engels in The Condition of the Working Class in England in 1844 spoke of "an industrial revolution, a revolution which at the same time changed the whole of civil society". Although Engels wrote his book in the 1840s, it was not translated into English until the late 19th century, and his expression did not enter everyday language until then. Credit for popularising the term may be given to Arnold Toynbee, whose 1881 lectures gave a detailed account of the term.[27]
Economic historians and authors such as Mendels, Pomeranz, and Kridte argue that proto-industrialization in parts of Europe, the Muslim world, Mughal India, and China created the social and economic conditions that led to the Industrial Revolution, thus causing the Great Divergence.[28][29][30] Some historians, such as John Clapham and Nicholas Crafts, have argued that the economic and social changes occurred gradually and that the term revolution is a misnomer. This is still a subject of debate among some historians.[31]
Lewis Paul patented the roller spinning frame and the flyer-and-bobbin system for drawing wool to a more even thickness. The technology was developed with the help of John Wyatt of Birmingham. Paul and Wyatt opened a mill in Birmingham which used their rolling machine powered by a donkey. In 1743 a factory opened in Northampton with 50 spindles on each of five of Paul and Wyatt's machines. This operated until about 1764. A similar mill was built by Daniel Bourn in Leominster, but this burnt down. Both Lewis Paul and Daniel Bourn patented carding machines in 1748. Based on two sets of rollers that travelled at different speeds, it was later used in the first cotton spinning mill.
The first successful piston steam engine was introduced by Thomas Newcomen before 1712. Newcomen engines were installed for draining hitherto unworkable deep mines, with the engine on the surface; these were large machines, requiring a significant amount of capital to build, and produced upwards of 3.5 kW (5 hp). They were also used to power municipal water supply pumps. They were extremely inefficient by modern standards, but when located where coal was cheap at pit heads, they opened up a great expansion in coal mining by allowing mines to go deeper.[70] Despite their disadvantages, Newcomen engines were reliable and easy to maintain and continued to be used in the coalfields until the early decades of the 19th century. By 1729, when Newcomen died, his engines had spread (first) to Hungary in 1722, Germany, Austria, and Sweden. A total of 110 are known to have been built by 1733 when the joint patent expired, of which 14 were abroad. In the 1770s the engineer John Smeaton built some very large examples and introduced a number of improvements. A total of 1,454 engines had been built by 1800.[70]
Until about 1800 the most common pattern of steam engine was the beam engine, built as an integral part of a stone or brick engine-house, but soon various patterns of self-contained rotative engines (readily removable but not on wheels) were developed, such as the table engine. Around the start of the 19th century, at which time the Boulton and Watt patent expired, the Cornish engineer Richard Trevithick and the American Oliver Evans began to construct higher-pressure non-condensing steam engines, exhausting against the atmosphere. High pressure yielded an engine and boiler compact enough to be used on mobile road and rail locomotives and steamboats.[71]
The development of bleaching powder (calcium hypochlorite) by Scottish chemist Charles Tennant in about 1800, based on the discoveries of French chemist Claude Louis Berthollet, revolutionised the bleaching processes in the textile industry by dramatically reducing the time required (from months to days) for the traditional process then in use, which required repeated exposure to the sun in bleach fields after soaking the textiles with alkali or sour milk. Tennant's factory at St Rollox, Glasgow, became the largest chemical plant in the world.
Canals began to be built in the UK in the late 18th century to link the major manufacturing centres across the country. Known for its huge commercial success, the Bridgewater Canal in North West England, which opened in 1761 and was mostly funded by The 3rd Duke of Bridgewater. From Worsley to the rapidly growing town of Manchester its construction cost 168,000 (22,589,130 as of 2013[update]),[90][91] but its advantages over land and river transport meant that within a year of its opening in 1761, the price of coal in Manchester fell by about half.[92] This success helped inspire a period of intense canal building, known as Canal Mania.[93] Canals were hastily built with the aim of replicating the commercial success of the Bridgewater Canal, the most notable being the Leeds and Liverpool Canal and the Thames and Severn Canal which opened in 1774 and 1789 respectively.
By the 1820s a national network was in existence. Canal construction served as a model for the organisation and methods later used to construct the railways. They were eventually largely superseded as profitable commercial enterprises by the spread of the railways from the 1840s on. The last major canal to be built in the United Kingdom was the Manchester Ship Canal, which upon opening in 1894 was the largest ship canal in the world,[94] and opened Manchester as a port. However, it never achieved the commercial success its sponsors had hoped for and signalled canals as a dying mode of transport in an age dominated by railways, which were quicker and often cheaper.
France was known for having an excellent system of roads at the time of the Industrial Revolution; however, most of the roads on the European continent and in the UK were in bad condition and dangerously rutted.[89][24] Much of the original British road system was poorly maintained by thousands of local parishes, but from the 1720s (and occasionally earlier) turnpike trusts were set up to charge tolls and maintain some roads. Increasing numbers of main roads were turnpiked from the 1750s to the extent that almost every main road in England and Wales was the responsibility of a turnpike trust. New engineered roads were built by John Metcalf, Thomas Telford and most notably John McAdam, with the first 'macadam' stretch of road being Marsh Road at Ashton Gate, Bristol in 1816.[97] The first macadam road in the U.S. was the "Boonsborough Turnpike Road" between Hagerstown and Boonsboro, Maryland in 1823.[96]
Steam locomotives began being built after the introduction of high-pressure steam engines after the expiration of the Boulton and Watt patent in 1800. High-pressure engines exhausted used steam to the atmosphere, doing away with the condenser and cooling water. They were also much lighter weight and smaller in size for a given horsepower than the stationary condensing engines. A few of these early locomotives were used in mines. Steam-hauled public railways began with the Stockton and Darlington Railway in 1825.[100]
Consumers benefited from falling prices for clothing and household articles such as cast iron cooking utensils, and in the following decades, stoves for cooking and space heating. Coffee, tea, sugar, tobacco, and chocolate became affordable to many in Europe. The consumer revolution in England from the early 17th century to the mid-18th century had seen a marked increase in the consumption and variety of luxury goods and products by individuals from different economic and social backgrounds.[125] With improvements in transport and manufacturing technology, opportunities for buying and selling became faster and more efficient than previous. The expanding textile trade in the north of England meant the three-piece suit became affordable to the masses.[126] Founded by Josiah Wedgwood in 1759, Wedgwood fine china and porcelain tableware was starting to become a common feature on dining tables.[127] Rising prosperity and social mobility in the 18th century increased the number of people with disposable income for consumption, and the marketing of goods (of which Wedgwood was a pioneer) for individuals, as opposed to items for the household, started to appear, and the new status of goods as status symbols related to changes in fashion and desired for aesthetic appeal.[127] 2ff7e9595c
