Quoted for truth. 70's symphonic prog is simply the most popular progressive music out there. There's a lot of terrific 70's prog albums out there, but there's just as much great stuff since 1980 as well. It's a shame that modern prog doesn't get nearly as much hype as the stuff from the 70's...

There's absolutely no reason why a Gauss curve should apply to the timeline of release year of the best prog albums.
If it did, that would mean that when checked from now, 2010, (and taking 1969 as the starting year of real prog) the best albums would cluster in the period around 1990, but when looked again in 2020 the best albums would have to be those around 1995, when obviously whatever happened between 2010 and 2020 can not have changed in any way the albums released around 1990 nor around 1995.
 
You should however find Gaussian curves in other features, for example the ratings. In principle you should expect to find most albums rated with 3 stars, a bit less albums with 2 or 4 stars (individually, when taken together 2+4 might outnumber the 3 stars) and even less in the 1 or 5 star regions.

Let me quote myself:  "The title is a joke, but the idea comes from a poll still open."

I'm wishing to discuss about why the golden period lasted only 5 years. Why those specific years and if there's a reason behind what happened later. 

It's not Math. Counting up the characteristics of the top 50 is neither statistics. Also because it's an indicator of PA people tastes, not necessarily about the absolute quality of the most rated albums and artists.

But there's no doubt that something started  to happen in the second half of the 70s and we had to wait for the 90s to have something back even if different.

The proper question may be: what happened and why ? and if you were nearby, how did you live that situation? 
What younger people thinks ? what they really know about that period ?

Feel free to ask different questions and/or give any kind of answers. 
I started the post without having in mind where to go. I hope we'll go somewhere otherwise the post will die on its own.

When I tried to found relate between "Rating" and "Masterpiece",most of you attack to me and talked about "Subjective" things. Now you discuss about "Statical parameters"(objective!). You discover! in some statical datas "The Golden Years in Prog History" and ignore subjective side of "The Top Ten List". You looking for "Objective" reasons and discuss about that. First I want to know How PA create these lists?Who rate these albums? I remember one guy told me collabs rate value is higher than ordinary listener rate.Is it true? and if it true How much? Now back to topic. Octopus-4 show me interesting true about one important parameter of Masterpieces : TIME.  Most of these albums released in 70's and after these 30/40 years they shine like brilliant. Just like "Wine" .Older wine is better than younger!!

What happened in 1977 ? Was prog killed by Punk and NewWave or people was just tired of pretentious 20 minutes suites? Did genres other than prog have the same destiny? 
When did the punk die? Wasn't about 1982? and the so-called new Wave? 

Is 5 years a sort of time limit ? 

"When a genre dies only the true art survives." Is it true or not?
Did social changes in the western world influence this change? Are we still changing?


Too many question marks. In my next reply I'll try to give some personal answers if possible.
I'm on CET, so I won't be back before 10 to 12 hours since now.

There are probably no truths, just opinions, I'l give mine but note that I'm from '66 so I was only 11 by '77, although I was already into prog from my older brothers and family.

Although other PA members will argue this, I don't think the prog audience got tired of prog by itself. Nor do I think that proggers turned into punks by themselves. I think it was the result of mass manipulation by the music industry who realised that prog was not a very profitable style. This was just the same as has been happening in every life and industry sector, the factual powers manipulate our tastes, fashions, etc in order to make us consume more and more, and preferably the things with which they make most profit.

New Wave lasted longer than Punk. I don't think there's any precise limit but linked to the above, the life cycle of fashions gets shortened in order to increase consumption. New products must be launched continuosly to the market, the faster the better (and music is a business product as well).

The ultraliberalism of the western culture has no doubt influenced the course of things in music as in everything else.
I want to believe that the true art survives but it may be a very struggling survival, we see so many wonderful ancient art which has become relegated to little more than the world of scholars and fans, with classical music being a prime example. For sure it is surviving, but in which conditions...

Let's correct the sentence:

The lists are calculated using weighted averages which takes into account the number of ratings and their relationship to the average number of ratings per album and the average rating of albums on this site. This is the same method that IMDB uses to create their top 250 films of all time. If you want to know more, look it up on Wikipedia.

Your technique of masking a secret, fiendish conspiracy by hiding in plain sight has worked brilliantly, Dean. Chesterton would be proud.

Hi. Thank you. Now I'm sure if you (PA)  want to BIAS one album or one style, You can do that. But I'm sure PA is the best prog site in the world (IMO) and honestly I trust to PA.

this fits the statistical expectations I have.no surprises here
Correct, but can you find a reason why it's so? 
 
partly because of the used algorhythm used for calculating the position on the charts, which favour a higher number of ratings.
 
personally I would drop the number of ratings if it exceeds the 200 ratings, after that the average rating should take over the importance over number of ratings. also I would drop the weighing of the rating sort (difference between review versus rating or even review by collab, or regular member difference is plain wrong and interferes with an accurate weighing system, which should be every rating counts as high as any other, its the number of ratings that ultimatly builds upo to a trustworthy average rating)
 
anyway.  If I'm correct they use a weighted rating system, which should do the trick quite nicely

How would we do that?
 
We have 253 collaborators on the site out of a total membership of  29,810 - even with a weighting of x2 we cannot begin to compete against a population 100 times larger.
 
If you consider the top 5 albums have 750-1000 ratings each and the vast majority of those ratings are from non-collaborators, (for example Selling England By the Pound has 986 ratings but only 98 collaborator reviews), so any bias we could attempt to create is easily beaten by the non-collab ratings.
 
Also, we cannot all agree on what is Prog so there is no way I, or anyone else, can convince 252 singleminded collaborators to bias a single album - it simply will not work.

PA is an open site on which everybody can register, even those who don't know anything of prog music.
Leaving the admins and designed experts the  possibility to decide who include or not and allowing them more weight on their ratings is a way, probably not the best, to avoid seeing Lady Gaga in the top 10. 

Of course it looks like the admin group contains more King Crimson and Van der Graaf fans than the average of the world population, but this is a fact.

However, what I'd like to see is a discussion about the possible causes of some events or at least discover that no events happened. Discussing PA was not the target of this thread.

So are you indirectly supporting the idea that punk was an invention of the media ? Did it gain popularity thanks to Top of the Pops ?

If so, was it part of a majors'  plan to kill the dinosaurs and sell low-cost music instead?
