Grapevine - Informal/Unofficial path of verbal communication (by means of gossip and rumor)
Some wise man claimed, "
Gossip is nature's telephone." ....and we'll soon discover, how!!! :)
The term comes from the expression, "grapevine telegraph", and was supposedly invented in US during the early 1850's, after the invention of telegraph in 1840's. Samuel Morse's first line was opened between Washington and Baltimore on 24th May 1844 and was an immediate success. The straight copper wires of electric telegraph were supposed to carry truthful information. The term "grapevine telegraph" came into being to accentuate the idea of distorted information that travels by word of mouth and drew its inspiration from the twisted stems of the grapevine (but like real telegraph is capable of transmitting vital messages quickly over long distances).
The first recorded usage, according to John Lighter in The Random
House Historical Dictionary of American Slang, was in a political
dictionary of 1852, which included the sentence "By the Grape Vine Telegraph Line .......we have received the following ".
There are various early
references that suggest that it was associated with clandestine communication among Southern blacks, especially the slaves and gained high popularity and acceptance during the American Civil War period.
Trivia: It was widely acknowledged that the blacks' communications
network was extremely useful to the Union cause, as John G. Nicolay
and John Hay reported in "Abraham
Lincoln: A History" in 1888,
calling it "one of the most important and reliable sources of
knowledge to the Union commanders in the various fields, which later in the war came to be jocosely designated as the 'grape-vine
telegraph'".
