The ETC had a monopoly of electrical telegraphy until the formation of the Magnetic Telegraph Company (commonly called the ''Magnetic'') who used a different system which did not infringe the ETC's patents. The Magnetic became the chief rival of the ETC and the two of them dominated the market even after further companies entered the field. The ETC was heavily involved in laying

Railway telegraphy continued to be an important part of the company's business with expenditure on the railways peaking in 1847–48. This focus on the railways was reflected in the directors and major shareholders being dominated by people associated with railway construction.

for £600. The relay allowed telegraph signals weakened over a long distance to be renewed and retransmitted onward.


Early years

The company was not immediately hugely profitable, and shares were more or less worthless. In 1846 it won a concession from Belgium for telegraph lines covering the whole country. The company installed a line from
Brussels Brussels (french: Bruxelles or ; nl, Brussel ), officially the Brussels-Capital Region (All text and all but one graphic show the English name as Brussels-Capital Region.) (french: link=no, Région de Bruxelles-Capitale; nl, link=no, Bruss ...
to Antwerp but the traffic was light (mainly stock exchange business) and the company decided to return its concession to the Belgian Government in 1850. In 1848, after a dispute with the Great Western over an engine the ETC was alleged to have damaged, the telegraph line from Paddington to Slough was removed, although the railway company continued to use the telegraph at the
Box Tunnel Box Tunnel passes through Box Hill on the Great Western Main Line (GWML) between Bath and Chippenham. The tunnel was the world's longest railway tunnel when it was completed in 1841. Built between December 1838 and June 1841 for the Great We ...
. The setback with the Great Western did not slow the growth of the telegraph along railway lines, and these continued to be the main source of revenue. By 1848 the company had telegraph lines along half of the railway lines then open, some 1,800 miles, and continued to make deals with more railway companies after that. These included in 1851 a new contract with Great Western which was extending its line to Exeter and Plymouth and by 1852 the ETC had installed a line that ran from London, past Slough, as far as

. These contracts usually gave the company exclusive rights to install telegraph lines. This gave the company a significant advantage over competitors when other companies entered the market. Other areas of growth were in the supply of news to newspapers, and contracts with stock exchanges. However, general use by the public was retarded by the high cost of sending a message. By 1855 this situation was changing. The ETC now had over 5,200 miles of line and sent nearly three-quarters of a million messages that year. The growth, together with competitors coming on to the market, drove down prices. ETC's maximum charge for an inland telegram (over 100 miles) fell from ten shillings in 1851 to four shillings in 1855. By 1859, growth required the company to relocate its London central office to Great Bell Alley,

establishing the company, the government reserved the right to take over the resources of the ETC in times of national emergency. This it did in 1848 in response to Chartist agitation. Chartism was a working-class movement for democratic reform. One of the main aims was to achieve the vote for all men over twenty-one. In April 1848, the Chartists organised a large demonstration at

and presented a petition signed by millions. The government, fearing an insurrection, used its control of the ETC telegraph to disrupt Chartist communication.


Competitors

The first competitor to emerge was the
British Electric Telegraph Company In the nineteenth century, the United Kingdom had the world's first commercial telegraph company. British telegraphy dominated international telecommunications well into the twentieth. Telegraphy is the sending of textual messages by human ope ...
(BETC), formed in 1849 by Henry Highton and his brother Edward. The ETC had a policy of suppressing competitors by buying up rival patents. This it had done to Highton when he patented a gold-leaf telegraph instrument. However, Highton now proposed a telegraph with a different system. Even worse for the ETC, in 1850 Parliament passed an Act giving it the right to force the railways to allow the BETC to construct a telegraph for government use between

and London. The ETC tried to oppose the government Bill but without success. A more serious rival came in 1851 with the formation of the English and Irish Magnetic Telegraph Company (later renamed the British and Irish Magnetic Telegraph Company and usually just called the ''Magnetic''). The Magnetic also used a non-infringing system, generating the telegraph pulses electromagnetically by the operator's own motion of working the equipment handles. The Magnetic got around the ETC's dominance of rail wayleaves by using buried cables along highways, a problem that had hindered the BETC and eventually led to its takeover by the Magnetic. Further, it had an exclusive agreement with the
Submarine Telegraph Company The Submarine Telegraph Company was a British company which laid and operated submarine telegraph cables. Jacob and John Watkins Brett formed the English Channel Submarine Telegraph Company to lay the first cable across the English Channel. An u ...
who had laid the first cable to France and was busily laying more cables to other continental countries. The Magnetic also beat the ETC in getting the first cable to Ireland in 1853. For a while then, the Magnetic had shut the ETC out of international business. The ETC was keen to correct this situation and started laying its own submarine cables. Other companies came on to the market, but ETC remained by far the largest of them with the Magnetic second. The ETC and the Magnetic so dominated the market that they were virtually a duopoly until nationalisation.


Submarine cables

The Electric Telegraph Company merged with the International Telegraph Company (ITC) in 1854 to become the Electric and International Telegraph Company. The International Telegraph Company had been formed in 1853 for the purpose of establishing a telegraph connection to the

s. The concession to lay the cables had originally been granted to the ETC, but the Dutch government objected to the ETC laying landlines on its territory so a separate company, the ITC, was set up to do this. In practice, the ITC was run by ETC staff. It planned to lay four separate cable cores as a diversity scheme against damage from anchors and fishing gear. All four were combined into a single cable in the sea a short distance from landing. The work was begun in 1853 with the ship ''Monarch'', specially purchased and fitted out for the purpose, and completed in 1854. The cable proved to need a great deal of maintenance and was replaced in 1858 by a single, heavier cable made by Glass, Elliot & Co and laid by ''William Cory''.


''Monarch''

The ''Monarch'' was the first ship to be permanently fitted out as a cable ship and operated on a full-time basis by a cable company, although the fitting out for the Netherlands cables was considered temporary. She was a

s to run the cable out of the hold and a powerful dedicated brake to control the cable running out. However, ''Monarch'' did not store the cable in water-filled tanks as was done on future cable ships. The ship could not, therefore, be kept in trim by replacing the cable with water as it was payed out. It was necessary to run out coils of cable alternately from the fore hold and the main hold for this reason. Besides the cables to the Netherlands, ''Monarch'' laid several cables around Britain in its first year. One of these was a cable across the

. A number of improvements were made to ''Monarch'' over the years and its gear became the prototype for future cable ships. A cable picking-up machine was soon fitted with a drum that could be driven by both steam engine and manual winching, designed by the company engineer, Frederick Charles Webb. In 1857, draw-off gear was fitted to avoid crew having to hold the cable taught by hand, and water-cooled brakes were fitted in 1863. The ship was frequently chartered to other companies like the Submarine Telegraph Company and the Magnetic for cable work. The first charter was to R.S. Newall and Company to recover an abandoned cable in the Irish Sea. Newall had made this cable for the Magnetic and a failed attempt to lay it from

Ireland

The chief competitor to the company, the Magnetic, had succeeded in providing the first connection to Ireland in 1853 on the Portpatrick–Donaghadee route. The ETC was keen to establish its own connection. In September 1854 ''Monarch'' attempted to lay a lightweight cable from Holyhead in Wales to

The primary system initially used by the company was the two-needle and one-needle Cooke and Wheatstone telegraphs. Needle telegraphs continued to be used throughout the company's existence, but
