Independent films normally go straight to DVD and do not go into cinemas. The reason for this is because of the low demand for them. A distributor would meet with the film producers and they would then split the profit. This is still a way that some films are distributed.
Now, however, there is a new way to distribute your film: self distribution. This has become a possibility due to viewing platforms such as iTunes, BitTorrent, Vimeo, and Netflix.
