About the 4A's

The 4A’s was founded as a national trade association to represent U.S. advertising agencies. These days, we provide counsel to members on everything from new business to succession planning to media transparency.

The 4A’s, founded in 1917, is the leading authority representing the marketing communications agency business. It provides leadership, advocacy and training that empowers agencies to innovate, evolve and grow. It serves 740 member agencies across 1,400 offices that control more than 85% of total U.S. advertising spend.

The 4A’s is committed to protecting the best interests of its members, their employees and the industry at large. Its Benefits division insures more than 164,000 agency professionals, and the D.C. office advocates for policies that best support a thriving advertising industry.

With its best-in-class learning and career development programs, 4A’s and its Foundation fuel a robust diversity pipeline of talent for its members and the marketing and media industry, fostering the next generation of leaders.

In honor of our 100th anniversary, we’re celebrating the people, agencies and ideas that drive the advertising business.
