This Horror Movie Math Will Make You Feel Really Old

For many of us, horror movies are the pinnacle of pop culture. So last night, when I was in the middle of my 3rd viewing of Scream recently, I had an interesting thought. The movie Scream came out in 1996, which was 24 years ago. This instantly made me feel old, but then I thought about how well the movie had held up. Minus the cell phone advancement and VHS tapes of course.

But 24 years is a long time, and I don't know if we have a proper frame-of-reference for that. If Scream is 24 years old now, what movies were 24 years old when it was released in 1996? 

When I constructed this frame of reference, it sent me down a rabbit hole of horror movie timelines. How long ago was a classic movie released, and what movie was that old when that movie was released? I know, it sounds crazy, and it might be hard to follow, so let me explain with these examples.
