Film (pronounced fill-um) is as much an artform as it is a business. It was originally developed as a means to display naked people "getting it on" and distributing it to the masses. Film is somewhat similar to movies, only much more pretentious.
Films are more commonly known as Brainwashing Sessions (pronounced Ber-rainwashing Sessions). This name came about from the Baze'd faces people get after watching films.
Early film was nothing like it is today, although in some ways it is more like films today than films today are. Some of the first films had no sound, or image, and were merely rough depictions of the acts that the director had invisioned. As the technology advanced, however, naked parts became much easier to discern. Still, there was no sound to go along with the pictures. It was at this time that "porno music" was invented to give the audience an auditory experience that at least somewhat fit the mood. Around this time people started saying, while watching films, where's the popcorn? So concession stands were built in lobbies. And it was good.
Soon, though, live sound was introduced, via talking parrots who were kept in a cage in the projection booth. This advancement brought forth the first big wave of film-making. Soon, films could be seen in any darkened theater, and were often shown to troops at war who were away from home, and thus, their punani.
Not long after, colour and higher picture quality came along. Industry executives and audiences alike were thrilled by the new images. These advances led to such film staples as the "close-up", which is now frequently followed by another staple: the "money shot". Also, film personalities gained mega-star status. People such as Ron Jeremy, Peter North, and Jenna Jameson are now household names. ;)
edit Film Today
Today, film is headed in a totally new direction. With the dawn of the Internet and the information age, the distribution of film is at a record high. Film can be obtained in 30 second clips from any number of free websites. Film has even made forays into e-mail distribution. It's hard to look anywhere and not see "MILFs", "BDSM", "ATM", and "Bukkake".
edit Developing Film
In the 1700s film was rather hard to develop especially when there wasn't any film to develop in the first place. The main problem was ladies wouldn't take their clothes off. If this occurred, the 30 hour developing time would have been for nothing as women with clothes on isn't porn and non existent porn rules out film alltogether. To get round this, the famous photographer Muybridge invented the x-cameraray which saw through the clothes thus taking a nude picture. Most women did not approve, except the lesbians.
