Washington Post Co to change name to Graham Holdings Co Mon Nov 18, 2013 9:20am EST (Reuters) - Washington Post Co is changing its name to Graham Holdings Co after it sold the Washington Post newspaper to Amazon.com Inc founder Jeff Bezos. The company's symbol on the New York Stock Exchange will change to "GHC" from November 29, Washington Post Co said on Monday. Washington Post Co, which also owns education services provider Kaplan, said in August it would sell its newspaper and other publishing businesses, as declining advertising revenue and readership hurt print media. The sale to Bezos closed on October 1. Reporting by Sagarika Jaisinghani in Bangalore; Editing by Maju Samuel
