"HOLLYWOOD" is spelled out in 45-foot (13. 7 m)-tall white capital letters and is 350 feet (106. 7 m) long. The sign was originally created in 1923 as an advertisement for a local real estate development, but due to increasing recognition, the sign was left up. The sign has been a frequent target of pranks and vandalism across the decades, but it has since undergone restoration, including the installation of a security system to deter vandalism. The sign is protected and promoted by The Hollywood Sign Trust, a nonprofit organization, while its site and the surrounding land are part of Griffith Park.
