" The term was coined in 1979 by Janice Dickinson, and gained currency by analogy with Andy Warhol's "superstars" of the 1960s, and, like "superstardom", it has been conflated to include almost anyone who finds steady access to work, uncommon in the highly volatile fashion industry. While the term gained steam in the 1980s, a number of models had become famous in their own right as far back as Dorian Leigh in the late 1940s . Amongst the first models whose name and face were familiar to those outside the fashion industry include Suzy Parker, a model in the 1950s, and Cheryl Tiegs in the 1960s. Others claim that Janice Dickinson has the right to the title of first supermodel since she is credited with the creation of the term. While still others claim Lisa Fonssagrives to be the world's first supermodel and none have surpassed her over 200 covers of Vogue alone. She was in every fashion magazine during the 1930s, 1940s and 1950s from Town and Country, Life, Vogue, the original Vanity Fair to the cover of Time. The high point of the supermodel era was in the 1980s and 1990s, with some of the most famous being "The Trinity" of Linda Evangelista, Naomi Campbell, and Christy Turlington.

Domain logic adds meaning to raw data e. g. calculating if today is the user's birthday or the totals, taxes and shipping charges for shopping cart items. View: This renders the model into a form suitable for interaction, typically a user interface element. MVC is often seen in web apps: the view is the html page and the code which gathers dynamic data for the page. Controller: This responds to events, typically user actions, and invokes changes on the model (but *not* the view). Builder Model Ship Many applications use a persistent storage mechanism (such as a database) to store data. MVC does not specifically mention this data access layer. "
