The advertising industry spends over $600 billion annually worldwide and $300 billion annually in the USA. The traditional structure includes advertisers who work with advertising agencies to develop campaigns. Agencies employ creative teams like copywriters, designers, and media buyers to develop campaigns and place ads through various media channels like TV, print, digital, and outdoor advertising. In South Africa, agencies typically charge hourly rates or commissions of around 15% of media spending, and work with a variety of external partners across the creative, research, production, technology, and media sectors.
