Silver Screen

So my last post got me wondering where the term silver screen came from. As many phrases we use with out question, the term at one point was quite literal. "A silver screen, also known as a silver lenticular screen, is a type of projection screen that was popular in the early years of the motion picture industry. The term silver screen originated in reference to the actual silver content embedded in the material that made up the screen's highly reflective surface. While actual silver screens are no longer commonly used, the term silver screen has passed into popular usage as a metonym for Hollywood and the movies..." Wikipedia
