据说香农是开发这个框架的先驱。这就是两方之间沟通的基本方式。在所有的传播模式和公共关系中都发现了类似的意识形态。最著名的公共关系模型之一是由gr& Hunt开发的模型。以下是gr& Hunt公司开发的4款与众不同的车型。gr& Hunt开发了4种与公共关系实践相关的独特模式。这些模型的开发是为了理解公共关系中存在的基本沟通类型，从而开发一个内聚模型。这四种模型分别是报刊绅士模型、公共信息模型、单向传播模型和双向对称模型。
The Shannon–Weaver model of communication states tries to provide the overall heuristics of communication. It fundamentally states the information is sent by a sender to transmit information to the other party. The sender is expected to have encoded a particular message through the medium. They are considered to be the encoders. They send information by using different portals and this is integrated rhetoric noises in the medium. This information is decoded by the portals or individuals before it reaches the final destination. There is ample feedback that has been garnered from this final receiver of the information. From the communication is developed. To elucidate with an example, when two people communicate using a medium the transmitter is assumed to be first person initiating the communication they then send it using a portal or devise. The information is decoded by other people who receive the digital sound signal and finally reaches the perception of the second person.
Shannon is said to have pioneered in developing this framework. This is how communication fundamentally occurs between two parties. Similar ideology is observed in all models of communications and in public relation. One of the most well known models of public relations is the models developed by Grunting & Hunt. The 4 distinctive models developed by Grunting & Hunt’s are explained in the following part. Grunting & Hunt developed 4 distinctive models related to public relation practices. These models were developed to understand the basic kinds of communication that exists in the public relation to develop a cohesive model. These four models are the press gentry model, public information model, one-way communication model and 2-way symmetric model.
