In what year was the famous 45 foot tall Hollywood sign first erected?

The famous 45-foot tall Hollywood sign was first erected in 1923, as a temporary advertisement for a real estate development called "Hollywoodland." The sign was made up of individual letters that spelled out "Hollywoodland" and was intended to stand for only eighteen months. However, due to its growing recognition and cultural significance, the sign became an iconic symbol of the American film industry and was eventually preserved and restored. Over the years, it has undergone several modifications and repairs, with the original "Hollywoodland" transformed into the now-familiar "Hollywood" we know today.
