The Past
This site http://www.precinemahistory.net provides a good history of the cinema history. Two other sites which explain the history equally as well Early Cinema and How Stuff Works (that site is also very interesting for other aspects of projection).
The Present
This site http://www.bksts.com/cin_proj.htm provides a good source of information on what it takes at the moment to be a projectionist.
The Future
The links given below should provide up to date information on what is currently happening within the industry. Find out what I think about this by clicking here. I have also written an update of what I think about Digital Cinema and is available either as a web page or a pdf file.
