The Hollywood Sign sits on Mount Lee in Griffith Park, overlooking Los Angeles. It was built in 1923 as "HOLLYWOODLAND" to advertise a new real estate development in the hills above the city. The Hollywood Chamber of Commerce shortened it to "HOLLYWOOD" in 1949, and the current metal letters date to a 1978 reconstruction funded by donors including Hugh Hefner and Gene Autry. The sign runs 350 feet across the hillside, with each letter standing 45 feet tall. A broadcast tower beside the sign transmits signals for several Los Angeles television and radio stations.
