Beginning in 1850, submarine telegraph cables allowed for the first rapid communication between people on different continents. The telegraph's nearly-instant transmission of messages across continents and between continents had widespread social and economic impacts. The electric telegraph led to Guglielmo Marconi's invention of wireless telegraphy, the first means of radiowave telecommunication, which he began in 1894.
