History: Modeling Agency, 1948, United States

The top agencies work with big-budget advertising agencies and fashion designers. They invest money into developing their talent so they can increase their status within the industry. These top agencies will help train models, get test shoots, layout portfolios, and put together comp cards (composition photo cards) and other printed materials models need.
The agencies find work for models by presenting them to designers, photographers, and ad agencies. The agencies are also responsible for booking the jobs, billing for the jobs, and eventually paying the models for their time. By handling the details, an agency allows a model to focus on modeling and not on the business end.
Because modeling is a very competitive, fast moving business that extends beyond the traditional 9 AM to 5 PM business hours, an agency generally conducts business 24 hours a day, to handle emergencies such as cancellations or rush jobs. Most agencies have a service or an operator to handle emergency issues after hours.
