Horror Timeline

Films have changed dramatically over the years, not just because of technology but because of audience expectations and feeling at the time. The best genre to look at for this is Horror. From Hitchcocks suspence movies in the 60s, to the modern psycological horrors - every decade produced classic horror films but all were very different.
