The ACM was founded in 1947 under the name Eastern Association for Computing Machinery, which was changed the following year to the Association for Computing Machinery. ACM is organized into over 171 local chapters and 37 Special Interest Groups (SIGs), through which it conducts most of its activities. Additionally, there are over 500 college and university chapters. The first student chapter was founded in 1961 at the University of Louisiana at Lafayette.

 

 

ACM brings together computing educators, researchers, and professionals to inspire dialogue, share resources, and address the field's challenges. As the U.S ’s largest computing society, ACM strengthens the profession's collective voice through strong leadership, promotion of the highest standards, and recognition of technical excellence. ACM supports the professional growth of its members by providing opportunities for life‐long learning, career development, and professional networking.

 

 

Founded at the dawn of the computer age, ACM’s reach extends to every part of the globe, with more than half of its nearly 100,000 members residing outside the U.S.  Its growing membership has led to Councils in Europe, India, and China, fostering networking opportunities that strengthen ties within and across countries and technical communities.  Their actions enhance ACM’s ability to raise awareness of computing’s important technical, educational, and social issues around the world.
