News The telegraph ushered in a new global communications regime, accompanied by a restructuring of the national postal systems, and closely followed by the advent of telephone lines. With the value of international news at a premium, governments, businesses, and news agencies moved aggressively to reduce transmission times. In 1865, Reuters had the scoop on the Lincoln assassination, reporting the news in England twelve days after the event took place.[121] In 1866, an undersea telegraph cable successfully connected Ireland to Newfoundland (and thus the Western Union network) cutting trans-Atlantic transmission time from days to hours.[122][123][124] The transatlantic cable allowed fast exchange of information about the London and New York stock exchanges, as well as the New York, Chicago, and Liverpool commodity exchanges—for the price of $5–10, in gold, per word.[125] Transmitting On 11 May 1857, a young British telegraph operator in Delhi signaled home to alert the authorities of the Indian Rebellion of 1857. The rebels proceeded to disrupt the British telegraph network, which was rebuilt with more redundancies.[126] In 1902–1903, Britain and the U.S. completed the circumtelegraphy of the planet with transpacific cables from Canada to Fiji and New Zealand (British Empire), and from the USA to Hawaii and the occupied Philippines.[127] U.S. reassertions of the Monroe Doctrine notwithstanding, Latin America was a battleground of competing telegraphic interests until World War I, after which U.S. interests finally did consolidate their power in the hemisphere.[128]
