There are a few possible explanations . According toGrunge , the idiom might date back to the development of the telegraphy scheme in the 1800s . to send and receive content , miles of telegraph line were string up on poles and knitted throughout the country .

The musical phrase grew in popularity during the Civil War , when communication through the “ grapevine ” became pressing .

Like most bars , rumors and rumormonger flowed freely , and it was therefore possible to see something at the Grapevine . While it did n’t forge the musical phrase , it may have helped popularize it .
