An advertising and media executive will help with the day-to-day progress of the whole advertising process, from receiving the brief from the marketing team, including objectives, budget, and timescales to the measurement of how effective the advertisement has been.
In their daily work, they will interact with many other people, processes, and systems. (For example, the client, 3rd party suppliers, and the broad team at the agency.) They help campaigns move forward, coping with inevitable setbacks and changes in direction (some at the last minute), whilst showing collaboration and maintaining relationships with all. Usually, they report to an Account or Media Manager.
