Annenberg Challenge: In 1993, the largest gift to public education was made by Ambassador Walter Annenberg, a $500 million grant named the Annenberg Challenge. The grant was designed to unite the resources throughout the United States and ideas of those committed to increasing the effectiveness of public schooling. Recognizing that no single gift could improve all schools, the Challenge served as a catalyst to energize and support educational reform efforts across the country.
Annenberg Institute for School Reform at Brown University: AISR was established at Brown University in 1993 through an anonymous gift of $5 million. Several months later, a $50-million gift – part of Ambassador Walter H. Annenberg's $500-million Challenge to the Nation to improve public education in America – enabled the fledgling Institute to expand the scope of its work. In appreciation of the Ambassador's gift, AISR was renamed in his honor. AISR adopted its current mission in 1998: “To develop, share, and act on knowledge that improves the conditions and outcomes of schooling in America, especially in urban communities and in schools serving disadvantaged children.“
The Annenberg Public Policy Center of the University of Pennsylvania: The Annenberg Public Policy Center of the University of Pennsylvania developed FactCheck.org. Factcheck.org monitors the factual accuracy of what is said by major U.S. political players in the form of TV ads, debates, speeches, interviews and news releases.
