Like all artforms, pornography has evolved over time—and this trailer for VintageErotica.com is a really great way to appreciate and understand that evolution.

Starting with the stag films of the 1910's, and going all the way up to the big haireds beauties of the '80s, the video shows a variety of clips from every decade along the way, making it very clear just how much has changed over the past century of porn—and, simultaneously, showing us just how much has stayed exactly the same.
