The alphabet spreads across the Mediterranean
Phoenician traders simplified writing into a small set of consonant signs; Greeks later added vowels, producing the ancestor of most scripts used today.

The Royal Road and the Persian courier system
Darius I built a 2,700-km road from Susa to Sardis with relay stations; couriers on fresh horses carried messages faster than anything before.
Paper reaches standardized production in Han China
Under Cai Lun's supervision the Han court standardized papermaking from mulberry bark, hemp and rags — cheap, light, writable surfaces.
Papermaking crosses into the Islamic world
After the Battle of Talas, papermaking — traditionally via captured Chinese craftsmen, more likely by gradual diffusion — reached Samarkand, then Baghdad, where mills soon supplied an empire's bureaucracy.
The Diamond Sutra: the oldest dated printed book
A woodblock-printed copy of the Diamond Sutra, made in 868 and bearing its own colophon, was preserved in Dunhuang's sealed cave library.
Bi Sheng invents movable type
The commoner Bi Sheng carved individual characters in clay that could be composed, printed and recomposed — recorded by the scholar Shen Kuo.
Gutenberg's movable-type press
Combining metal movable type, oil-based ink and a screw press, Gutenberg printed the 42-line Bible; within decades presses spread across Europe.
'What hath God wrought': the telegraph
Samuel Morse's line between Washington and Baltimore carried the first formal message in code — information traveling without any physical carrier to see.
The transatlantic cable holds
After the 1858 cable failed within weeks, the Great Eastern laid a durable one in 1866: Europe and North America wired together on the ocean floor.
Bell patents the telephone
Alexander Graham Bell's patent — hours ahead of a rival filing — turned the telegraph's clicks into the human voice over wire.
Marconi signals across the Atlantic
Guglielmo Marconi's system received the letter S in Morse code at St John's, Newfoundland — the first transatlantic wireless transmission.
ARPANET sends its first packets
The first node at UCLA attempted to log in to a machine at SRI; the system crashed after 'LO' — but packet switching worked, and the network grew.
TCP/IP flag day
On January 1, 1983, ARPANET switched from NCP to TCP/IP — a coordinated cutover that made 'internetworking' the network's native language.
The World Wide Web opens to everyone
Tim Berners-Lee's CERN project — URLs, HTTP, HTML — was released royalty-free; by 1993 Mosaic made it visual, and the web took over the internet.
GSM makes phones universal
The first GSM call was made in Finland in 1991; a shared European standard for digital mobile telephony spread worldwide, with SMS as an afterthought.
VoIP: voice becomes data
VocalTec's InternetPhone let two computers talk over the public internet; engineers then built SIP, codecs and gateways until voice was just another application.
