1963: The Moscow-Washington hotline, which became known in pop culture as the "red telephone," is established between the Soviet Union and the United States following the Cuban Missile Crisis. Despite its popular name, the hotline was never a telephone line and no red phones were used. The system first used teletype equipment, which was replaced by facsimile units in 1988 and a secure computer link for email in 2008. The hotline transmitted its first test messages on Aug. 30, 1963, with Washington sending Moscow the text "The quick brown fox jumped over the lazy dog's back 1234567890" to ensure all the keys on the teletypes were in working order. The Soviets sent back a poetic description of Moscow's setting sun.
