IGA -Independent Grocers Association.- is a name used by many independent grocery stores throughout the world. It has since expanded to the world's largest voluntary supermarket chain, where the IGA banner is licensed in 45 countries and territories to over 4,000 independent supermarkets served by 37 independent distributors.
IGA was started in the United States in May 1926 when a group of 100 independent retailers in Poughkeepsie, New York, and Sharon, Connecticut, led by J. Frank Grimes, began operating as the Independent Grocers Alliance. This group quickly expanded, and by the end of the year there were more than 150 IGA retailers. In 1930 there were over 8,000 grocery stores using the IGA name. The company uses the "Hometown Proud Supermarkets" slogan.
Today, many IGA grocery stores are still located in smaller cities and towns throughout the United States, such as Sedona, Arizona; Calistoga, California; Moultrie, Georgia; East Hampton, New York; Minerva, Ohio; Minster, Ohio; Olmsted Falls, Ohio and Killeen, Texas.
