To hear something through the grapevine is to learn about something. It can also simply refer to an overheard conversation or anonymous sources of information, e.g. "I heard through the grapevine that Brad died."
|“||Often the slaves got knowledge of the results of great battles before the white people received it. This news was usually received from the coloured man who was sent to the post office for the mail... The man who was sent to the post office would linger about the place long enough to get the drift of the conversation from the group of white people who naturally congregated there, after receiving their mail, to discuss the latest news. The mail carrier on his way back to our master's house would as naturally retell the news that he had secured among the slaves, and in this way they often heard of important events before the white people at the 'big house,' as the master's house was called.||”|
However, the New York Public Library contends that the phrase derives from the infamous Grapevine Tavern in New York City's Greenwich Village. During the Civil War it "...was a popular hangout of Union officers and Confederate spies... It was the ideal place to get news and information, or in the case of spies and politicians, the ideal place to spread rumors and gossip, leading to the popular phrase 'heard it through the grapevine'."
Grapevine communication existed from the American Civil War to the First World War. It was coined this because of its nature of networking and reaching several at once; it causes the transformation of information between one individual and another.

Flexibility: There is no formal control over grapevine, so it is more flexible than other forms of communication. This also makes it more vulnerable and problematic, as one cannot send a message to any specific person, but is rather putting faith in the vagaries of luck, having no idea how many people, or who, might eventually hear the communication. Compare this to sending a letter to a person, or telephoning them, for example.
Rapid communication: It is faster than many other forms of communication such as the postal service or posting bulletins.
No record: There is no evidence which can be documented for future reference.
Distortion: The message which is passed gets distorted when it passes from one person to another.
Spontaneity: Grapevine communication is spontaneous as it is passed automatically from the top level of the organization to the bottom level without any difficulty in delivering the message. It is used by management to spread information that either cannot be shared officially or in an attempt to test the waters.
Cheap: It does not require any funds to take place. However, it can cost the speaker money if there are negative consequences of messages being garbled in transmission from person to person, or if they fail to receive the message through some misunderstanding, such as others believing they were already informed, since there is no control over or record kept of the communication and thus no idea of who heard it, when they heard it, or even what they actually heard.
