The history of telecommunication began with smoke signals and drums in Africa, Asia, and the Americas. In the 1790s, the first fixed semaphore systems emerged in Europe. However, it was not until the 1830s that electrical telecommunication systems started to appear. Technology was making rapid progress, and work soon turned to make more efficient use of existing telegraph infrastructure and the transmission of sound. The first commercial telegraph line opens in London (1837). The first subsea telegraph line opens between England and France (1850). German inventor Johann Reis transmits his voice to another room using his “telephone” (1861).
