1866 CE

For all prior history, information travelled at the speed of its carrier: a rider, a ship, a pigeon. The telegraph broke that tie, and the transatlantic cable of 1866 joined the New York and Liverpool cotton markets almost in real time. Economists have measured the effect like an experiment: the price gap between the two shores narrowed and steadied, trade grew and responded faster to demand, with efficiency gains estimated at 8 percent of export value.
Why it matters
This is the moment the planet acquired a nervous system, and the point at which information itself, apart from the goods it described, showed a price of its own. Markets, news and diplomacy began working at electric speed while everything physical still moved by steam. Every later acceleration replays it: telephone, internet, trading algorithms. The cable is still studied for the same reason, to price what an information friction costs.
Dating & uncertainty
Land telegraphy spread from the 1840s; 1866 marks the transatlantic cable that held, when news between the two great cotton markets went from ten days by ship to a day. The measured effects concern trade: price gaps between New York and Liverpool shrank and steadied, exports rose, and a reanalysis of the American rollout argues the distortions removed were about half as large as first estimated.
