ReThink History: Can You Hear Me Now

Let's ReThink History

For most of history a message moved only as fast as the person carrying it. Then it moved at the speed of sight: a fire on a hill, a flag on a mast, a semaphore arm on a tower. Then it moved as electricity, then as radio waves, then as pulses of light in glass. Today it moves by laser between satellites. Each leap made the last one look quaint. The telegraph replaced the courier, the telephone replaced the telegram, and the phone in your pocket replaced the phone booth. Can You Hear Me Now is a fourteen-part ReThink History series on the trajectory of telecommunications. It begins with beacon fires and signal flags. It follows Morse code from telegraph wires to signal mirrors to a prisoner of war blinking a message to the world. It covers the cable laid under the Atlantic, the telephone monopoly that wired a nation, radio and television on the public airwaves, the glass fiber and digital code that carry nearly everything now, the cell tower and the satellite. In every era it asks who owned the channel. The series ends in October 2026, when companies began putting AI data centers into orbit, and it tests a bold forecast honestly against the physics, the economics and the history of failed predictions: that machines, not people, are becoming the network's main customers, and that this will make the cell phone itself quaint.

  1. Episode 1

    Ep 1: Fire on the Hill

    When a signal can only say yes or no, how much can it really carry? In a play first staged in Athens in 458 B.C., a watchman waits a year on a palace roof for one fire on the horizon. On 8 May 2025 the world waited on a chapel chimney in Rome for the same kind of signal. This opening episode follows the oldest channel on Earth: Greek and Byzantine beacon chains, the Korean bongsu with its scale of five torches, the Apache, Lakota and O'odham smoke signals that nineteenth-century observers compared to the telegraph, and the Congo basin drummers who broke the beacon's limit by making a drum speak. That limit was named by the Greek historian Polybius more than two thousand years ago: a fire can say only what both ends agreed before anything happened. In the language of information theory, one beacon carries one bit. The episode also gives full weight to the objection that none of this was "telecommunication" at all, a word not coined until 1904. In this episode: • Aeschylus's beacon speech and the one-bit limit • The Byzantine line and its twelve-hour clock code • Smoke signals, from documented sources • Talking drums, and what still survives of the oldest channel You're at the start: this is Episode 1 of 14, and the series runs in order.

  2. Episode 2

    Ep 2: Flags, Arms and Placards

    In 1836 France discovered that its own state telegraph had been carrying Paris bond prices to two bankers in Bordeaux for about two years. The courts found that no law forbade it. The bankers had bribed operators near Tours to slip deliberate errors into official messages on the Chappe telegraph, a chain of towers with moving wooden arms that only the state could use. The next year France passed a law. This episode follows the channel that came between the beacon and the electric wire: the Chappe network, which by 1844 linked twenty-nine cities over about five thousand kilometers; the shutter telegraph from London to Deal; and the flag codes of the sea, from Nelson's twelve-hoist "England expects" at Trafalgar to the International Code of Signals. It was slow, it went blind in fog and at night, and the electric telegraph made it quaint within a lifetime. Yet a version of it rides on almost every fuel truck on an American highway: the hazardous-materials placard, a visual code read at speed by first responders. In this episode: • The Chappe brothers' towers, and a state monopoly on messages • The Bordeaux bankers and the Count of Monte Cristo • Popham's flag code and Trafalgar • Hazmat placards and the Emergency Response Guidebook New here?

  3. Episode 3

    Ep 3: Dots, Dashes and Blinks

    On 2 May 1966 a captured American naval aviator, Jeremiah Denton, sat before a camera in Hanoi and blinked one word in Morse code: T-O-R-T-U-R-E. United States naval intelligence read the word off the film. It was the first clear confirmation that American prisoners were being tortured. Behind the prison walls his fellow prisoners used a different code: not Morse, but a five-by-five grid of letters tapped out by row and column, first used in a Hoa Lo cell in June 1965, whose ancestor a Greek historian described for signal fires. This episode follows the dot and the dash off the telegraph wire: onto the Army's heliograph mirrors in the 1886 campaign in Arizona and New Mexico, onto ships' lamps and the first wireless sets, and into S-O-S. Then it traces Morse's long retreat, to the full start of the Global Maritime Distress and Safety System on 1 February 1999 and the end of the Morse requirement for American amateur licenses in 2007, and gives Morse's champions their case that the oldest digital code was never obsolete in a crisis. In this episode: • Denton's blinked message, told with care • The tap code is not Morse • Heliographs and the 183-mile record • S-O-S, five hundred kilohertz and the 1999 cutover • Ham radio and what survives New here?

  4. Episode 4

    Ep 4: What Hath God Wrought

    On 1 May 1844, news that the Whigs had nominated Henry Clay left Baltimore on a train and reached the Capitol about an hour before the train did. Once news can outrun the train, who owns the news? Alfred Vail had sent it ahead on a wire. Three weeks later Samuel Morse sent "What hath God wrought," and the telegraph broke the link between the speed of a message and the speed of the person carrying it. This episode follows the thirty-eight-mile line Congress paid thirty thousand dollars to test, the government's decision to let it go, the railroads that ran their trains by telegraph and set the nation's clocks in 1883, and the transcontinental line finished on 24 October 1861, two days before the Pony Express was terminated after eighteen months. By 1866 Western Union carried a reported ninety percent of American telegraph traffic, and its alliance with the Associated Press shaped much of the news. The episode gives that alliance its strongest case, meets the operators, including women and the eight thousand who struck in 1883, and follows the telegram from two hundred million a year at its peak to its last American day in January 2006. In this episode: • Morse, Vail and the race with the train • Railroad time and the Pony Express • Western Union and the Associated Press: who owned the wire and the news • The operators, and the last telegram New here?

  5. Episode 5

    Ep 5: The Wire Under the Sea

    In August 1858 a ninety-eight-word message from Queen Victoria took about sixteen hours to cross the first Atlantic cable. Within weeks the cable was dead. How did that failure become the channel that still carries almost everything between continents? This episode follows a copper wire wrapped in tree gum, the paper merchant Cyrus Field, and the voltages that most investigators concluded burned out the 1858 cable. It took eight more years, the physicist William Thomson's theory of how signals crawl through a long wire, and the Great Eastern, the largest ship in the world, to lay a cable that lasted in 1866. Then the cables multiplied along routes chosen to land on British soil, and in August 1883 the telegraph carried news of Krakatoa from Java around the world in what the writer Simon Winchester calls the first global news event. Today, by TeleGeography's estimate, more than a million and a half kilometers of cable lie on the seabed, increasingly owned by the companies that run the internet, and satellites carry only a fraction of one percent of American international capacity. In this episode: • 1858: the salute, the silence and the blame • Thomson, gutta-percha and the Great Eastern • The imperial cable network and Krakatoa • Undersea cables now: Google, Meta, faults and sabotage fears New here?

  6. Episode 6

    Ep 6: Mr. Watson, Come Here

    On 10 March 1876 the first words anyone wrote down as heard over a telephone were a request for a man to walk into the room. Who invented the telephone, and who came to own the wire? Alexander Graham Bell's patent, number 174,465, had been issued three days earlier, after papers from Bell and Elisha Gray reached the Patent Office on the same day, a race still argued, with Antonio Meucci of Staten Island claiming to have been first of all. Out of that patent grew the Bell System. It fought about six hundred lawsuits, outlasted most of its rivals and, under Theodore Vail, made a bargain with the government: "One Policy, One System, Universal Service." This episode meets the operators, more than three hundred fifty thousand in the late 1940s, almost all of them women; the automatic switch that replaced them; the farmers who strung their own lines; and the phone booth and the message unit that the cell phone made quaint. It gives the monopoly its strongest case, including eleven Nobel Prizes for work at Bell Labs, and ends with the copper landline AT&T says it will mostly retire by 2029. In this episode: • Bell, Gray and Meucci: what is contested • Vail's bargain and the Kingsbury Commitment of 1913 • Operators, the automatic switch and party lines • The phone booth, the message unit and the end of copper New here?

  7. Episode 7

    Ep 7: Through the Air

    On the night the Titanic sank, the operator of the nearby Californian took off his headphones and went to bed. Fifty-eight nautical miles away, the Carpathia's operator heard the call only because he had kept his headset on. Who should control the air, and who has to be listening? This episode follows radio from Maxwell's equations of 1865 and Hertz's experiments to Guglielmo Marconi, who filed his British patent at twenty-two and whose company decided which stations it would talk to. After the Titanic, the Radio Act of 1912 required federal licenses. On election night 1920, K-D-K-A in Pittsburgh read presidential returns to anyone listening, and within a few years hundreds of stations crowded the same narrow band. Congress answered with a principle: a broadcaster may use a channel in the "public interest, convenience, or necessity," but may never own it. Television arrived inside that bargain, after Philo Farnsworth's patent fight with the Radio Corporation of America, and by 1961 the chairman of the Federal Communications Commission was calling it "a vast wasteland." The episode gives the case for licensing the airwaves and the case against it their full strength. In this episode: • Maxwell, Hertz and Marconi • The Titanic and the Radio Act of 1912 • K-D-K-A, spectrum chaos and the Communications Act of 1934 • Farnsworth versus RCA, and the "vast wasteland" New here?

  8. Episode 8

    Ep 8: Light in a Glass Thread

    In 1966 the best glass fibers lost almost all their light within about twenty meters. An engineer in an English laboratory said that, made pure enough, they could carry telephone calls for kilometers. Most experts did not believe him. In two years at one laboratory, Bell Labs produced the transistor (December 1947) and Claude Shannon's theory of information (1948), which treated every message as a stream of bits. Then Charles Kao and George Hockham proposed glass as the channel, Corning made it in 1970, and by 1988 the first transatlantic fiber cable carried about forty thousand calls at once. Meanwhile a Defense Department network learned to link networks, and the federal government broke up AT&T on 1 January 1984. Then came the forecast: beginning in 1998, WorldCom executives said internet traffic was doubling every hundred days. Actual traffic was by then doubling about once a year. In the two years before mid-2001 companies spent some thirty-five billion dollars laying about a hundred million miles of fiber, and in June 2001 about five percent of it was in use. WorldCom filed for bankruptcy in July 2002. In this episode: • The transistor, Shannon and the bit • Kao, Corning and the purest glass • ARPANET, TCP/IP and the AT&T breakup: both cases • The hundred-day myth and the fiber glut New here?
