In the context of the film and television industries, to greenlight is to give permission to proceed with a project. It specifically refers to formally approving its production finance and committing to this financing, thereby allowing the project to proceed from the development phase to pre-production and principal photography. The power to greenlight a project is generally reserved to those in a project or financial management role within an organization. The process of taking a project from pitch to green light formed the basis of a successful reality TV show titled Project Greenlight. The term is a reference to the green traffic signal, indicating "go ahead".
