Founded in 1935 by George Gallup, Gallup began as a pioneering market research company. George Gallup, a journalism professor and advertising researcher, developed scientific sampling techniques to measure public opinion accurately. His innovative approach to polling gained widespread recognition after correctly predicting Franklin D. Roosevelt's victory in the 1936 U.S. presidential election, contrary to other popular polls at the time. Today, Gallup is privately held and led by Jim Clifton, who became CEO in 1988. Gallup is headquartered in Washington, D.C., with offices worldwide. They primarily focus on analytics and advice related to public opinion polling, covering topics such as politics, economics, wellbeing, and workplace issues. Their research spans global issues, national concerns, and organizational challenges. Gallup is perhaps best known for its political polls and presidential approval ratings, but they also conduct extensive research on employee engagement, customer satisfaction, and social issues. One interesting fact: A unique aspect of Gallup is its World Poll, launched in 2005, which continuously surveys residents in over 160 countries, representing 98% of the world's adult population. This massive undertaking provides a comprehensive, ongoing measure of global public opinion on a wide range of topics.
