Prog Rock Primer album releases over time

I next thought it would be interesting to see how progressive rock music developed over time, starting from the end of the 60s and moving as near as possible to the present day. In this case that means 1968 through to 2014. This whole exercise will need repeating again to see if any releases this year (2015) feature in the future.

The distribution of releases looks like this:
