television: [20] Television means etymologically ‘far vision’. Its first element, tele-, comes from Greek téle ‘far off’, a descendant of the same base as télos ‘end’ (source of English talisman and teleology). Other English compounds formed from it include telegraph [18], telegram [19], telepathy [19] (etymologically ‘far feeling’, coined by the psychologist Frederic Myers in 1882), telephone [19], telescope [17] (a word of Italian origin), and telex [20] (a blend of teleprinter and exchange). Television itself was coined in French, and was borrowed into English in 1907.

Of its abbreviations, telly dates from about 1940, TV from 1948.
