Encoding/decoding model of communication

The encoding/decoding model of communication emerged in rough and general form in 1948 in Claude E. Shannon's "A Mathematical Theory of Communication," where it was part of a technical schema for designating the technological encoding of signals. Gradually, it was adapted by communications scholars, most notably Wilbur Schramm, in the 1950s, primarily to explain how mass communications could be effectively transmitted to a public, its meanings intact by the audience (i.e., decoders).
