The Network, by Scott Woolley, tells the history of wireless communications, and the stories of the characters that were a part of it. It’s the first book strictly about media history that I’m summarizing and adding to my best media books list. Wireless communications start with wired communications Wireless communications today of course include cell phones, but The Network takes us from the wireless telegraph, to radio, to television, and finally to satellites. First, it gives a little background on the history of the electric telegraph, the invention which suddenly made it possible to move, in minutes, messages that used to take weeks to reach their destinations. The electric telegraph was able to change the world thanks to one simple action: The ability to move a piece of metal at the end of a wire. That was enough to develop codes that could transmit messages, based upon the simple movement of that piece of metal. This process started in 1822, when Christian Órsted attached a copper wire to a battery and saw a nearby compass needle move. There was a several-decade-long race to develop an electric telegraph. The first transatlantic cable was opened for business by 1866. A big customer of these telegraph services were stock traders, who could buy shares in London, sell them a few seconds later in New York, and always profit if their trades were executed in time. Morse code was the winning format for turning the movement of a piece of metal into messages that could travel around the world. A claim in The Network I couldn’t find a source for, but that sounds pretty cool: The clouds in New York City at night used to have projected on them news, election results, and sports scores – in Morse code. From a worthless accidental discovery to worthwhile wireless The history of wireless communication started with a discovery as accidental as Christian Órsted’s: Heinrich Hertz noticed that metal objects moved slightly when lightning struck nearby. He later conducted experiments where he successfully generated sparks through the air. It was pretty cool, but he concluded that the invisible waves he had discovered were “of no use whatsoever.” Electrical signals that traveled through the air were made very useful, indeed, by Italian inventor Guglielmo Marconi. For much of its early years, most people thought his Marconi Company was a scam. Like the dot-com and crypto booms, many companies at the dawn of wireless technology made off with investors’ money. One article, with the headline, “Wireless and Worthless,” pointed out that more criminals were being prosecuted from wireless companies than from any other industry. Besides, what did we need wireless technology for, when there were companies such as The Commercial, which was probably the hottest tech company in New York in the early 1900s? It owned five of the sixteen cables crossing the Atlantic Ocean, and one of the two that crossed the Pacific – which was 10,000 miles long. 10,0
