A View is a visual representation of a Model, retrieving data from the Model to display to the user and passing requests back and forth between the user and the Model. In their final design, a Model represents some part of the program purely and intuitively. After discussing it with the other Smalltalk developers, he and the rest of the group settled on Model, View, and Controller instead. His design initially had four parts: Model, View, Thing, and Editor. : 330 He wanted a pattern that could be used to structure any program where users interact with a large, convoluted data set. Trygve Reenskaug created MVC while working on Smalltalk-79 as a visiting scientist at the Xerox Palo Alto Research Center (PARC) in the late 1970s.

One of the seminal insights in the early development of graphical user interfaces, MVC became one of the first approaches to describe and implement software constructs in terms of their responsibilities. Popular programming languages have MVC frameworks that facilitate the implementation of the pattern. Traditionally used for desktop graphical user interfaces (GUIs), this pattern became popular for designing web applications. This is done to separate internal representations of information from the ways information is presented to and accepted from the user. Model–view–controller ( MVC) is a software architectural pattern commonly used for developing user interfaces that divide the related program logic into three interconnected elements.
