60 free Communication trivia questions with answers — technology quiz, new questions added Aug 2026.
Every leap in human communication left a great trivia question behind: the four words Samuel Morse tapped out in 1844, the two words in the first text message, the reason the @ sign is in every email address, and why a Danish king's nickname is on your headphones. This communication trivia quiz walks through the whole history, from cuneiform and the Rosetta Stone through printing, postage stamps, semaphore, the telegraph and telephone, radio and television, and on to the internet, mobile phones, emoji and hashtags. There are also questions on the languages and codes people built to be understood: Braille, American Sign Language, Esperanto, the NATO phonetic alphabet, SOS, Mayday and 10-4, plus a few on communication theory, from Marshall McLuhan's most famous line to the 7-38-55 rule and Claude Shannon's 1948 paper. It suits a technology round at a pub quiz, a classroom unit on media history, or a team icebreaker for anyone whose job involves talking to other people. Every answer was checked against encyclopaedic and primary sources before publishing, and each question carries a citation.

7 March 1876
US Patent 174,465 was issued on 7 March 1876, a few days before Bell's famous 'Mr Watson, come here' call; Meucci, Reis, Bourseul and Elisha Gray have all also been credited with inventing the device.
Q 05Which inventor is credited with popularising 'hello' (or 'hullo') as the standard telephone greeting?
Thomas Edison
Thomas Edison suggested 'Hello' in an 1877 letter about how to open a telephone call, while Bell favoured 'Ahoy'; the word spread through early exchange operators, nicknamed 'hello girls'.
Q 06In which year did Ray Tomlinson send the first email between users on different ARPANET hosts?
1971
In late 1971 Ray Tomlinson, at BBN, sent a test message between two side-by-side PDP-10 computers, picking the @ sign to separate the user's name from the machine's.
Q 07What did the very first SMS text message, sent over the Vodafone network in 1992, say?
Merry Christmas
Engineer Neil Papworth typed 'Merry Christmas' on a computer and sent it to Vodafone director Richard Jarvis's Orbitel phone at a party in Newbury on 3 December 1992; he later said 'it didn't feel momentous at all'.
Q 08Tim Berners-Lee invented the World Wide Web in 1989 while working at which organisation?
CERN
At CERN, the particle physics laboratory near Geneva, Berners-Lee wanted a way to share documents across a large, constantly changing lab; CERN put the Web software in the public domain in 1993.
Q 09The Pony Express cut coast-to-coast message time to about ten days, but operated for only how long?
18 months
The Pony Express ran about 18 months, from April 1860 to October 1861, closing two days after the transcontinental telegraph was completed; it was quickly romanticised into Old West legend.

Issued on 1 May 1840, the Penny Black carried a profile of Queen Victoria based on a portrait made when she was 15, and was Sir Rowland Hill's idea for showing that postage had been prepaid.
Q 11Who invented the most widely used optical telegraph, a chain of towers with pivoting arms, in France in 1792?
Claude Chappe
Claude Chappe's system of pivoting arms on tower tops first linked Paris and Lille in 1794; the word 'telegraph' itself was suggested for it by the statesman Miot de Mélito.
Q 12How old was Louis Braille when he developed his tactile writing code in 1824?
Fifteen
Braille was fifteen, a pupil at the Paris institute for blind youth, when he improved on Charles Barbier's 'night writing', which used 12-dot cells for 36 sounds; Braille cut the cell to six dots.

Laurent Clerc
Q 21Which satellite, launched in July 1962, relayed the first live transatlantic television feed?

UCLA student Charley Kline typed 'LO' to Bill Duvall at the Stanford Research Institute at 10:30 pm before the system crashed; Telnet and FTP followed once the Network Control Program was written in 1970.
Q 23Martin Cooper made the first handheld cellphone call in 1973 while working for which company?
Laurent Clerc, a deaf teacher from the Paris institute, sailed to America with Gallaudet in 1816; the school blended French Sign Language with local sign systems such as the one used on Martha's Vineyard.
Q 14Why was SOS adopted as the international distress signal in 1906?
Simplicity of its Morse pattern
SOS stands for nothing at all; it was chosen at the 1906 Berlin convention for the simplicity of its Morse pattern, an unbroken three dots, three dashes, three dots, replacing Marconi's CQD.
Q 15The word 'emoji' comes from Japanese words meaning what?
Picture and character
Emoji means 'picture and character', from e (picture) plus moji (character); its resemblance to 'emotion' and 'emoticon' is pure coincidence, and the first sets came from Japanese device makers in the late 1980s and 1990s.

Scott Fahlman
Scott Fahlman posted the proposal on 19 September 1982 to mark jokes; Vladimir Nabokov had mused in a 1969 interview that there ought to be a typographical sign for a smile, 'some sort of concave mark'.

Q 20Queen Victoria's 1858 telegram, the first official one across the Atlantic cable, went to which US president?
James Buchanan
James Buchanan replied to Victoria's greeting, which had taken about 16 hours to transmit; the cable, laid by Cyrus Field's Atlantic Telegraph Company, soon failed after Wildman Whitehouse applied far too much voltage.
Motorola
Motorola's Martin Cooper rang his rival Joel Engel at Bell Labs from a Manhattan sidewalk on 3 April 1973 using a DynaTAC prototype; the phone did not reach the market until 1983.
Q 24Who first proposed using hashtags on Twitter, in a 2007 tweet?
Chris Messina
He never tried to patent the idea, saying hashtags 'were born of the internet, and owned by no one'.
Q 25What was Twitter's original character limit per post, in force until 2017?
