What is the name of the foundation founded by the publisher of TV Guide and the Philadelphia Inquirer?

The foundation founded by publisher Walter Annenberg is the Annenberg Foundation.

Walter H. Annenberg built a major publishing empire through Triangle Publications, whose holdings included The Philadelphia Inquirer and TV Guide. He established the Annenberg Foundation in 1989 after selling much of that media empire.

The foundation’s name is sometimes confused with the Annenberg School for Communication, which Walter Annenberg also helped establish through major gifts. The school and the foundation are separate institutions, even though both carry the family name.

Annenberg’s philanthropy reached beyond publishing. His giving supported education, communications, the arts, public broadcasting, and civic initiatives. His earlier creation of TV Guide helped make him one of the most influential media publishers of his era.
