There are a few functions that I know VG Chartz hasn't implemented (yet, anyway), and I figured that I could provide some of those on my own site by compiling the data provided here each week to analyze 2008 as it progresses.  What I have so far can be found here:

 If the higher-ups at VG Chartz would prefer I not do this, then I'll gladly take it down.  I just figured it'd be nice to have another way of looking at VG Chartz data as it comes in.  If they're alright with it, then I'm open to suggestions on other calculations to make.  Though try to keep it to stuff that's not available or easily accessible at VG Chartz.  Enjoy!

very nice, I have often wished I did not have to crawl through worldwide weekly charts to go back and view the progression.

That's a great idea.

The charts look great skyRender, i like the percentages for each week.

I like that view (in addition to what the site has). Over 2008 that particular view should make for some interesting viewing.

That was the idea behind it. VG Chartz data right now gets compiled with handheld and console data combined, which is fine for a full-market view, but doesn't really give a clear view on how the three newer consoles specifically are doing compared to one another on a week-by-week basis.

For those interested, I just updated the data to include comparisons of DS and PSP (apart from the consoles, of course; the entire idea here is to provide comparisons of modern systems that segregate handheld and console markets).

sweet action!!!

I was always wonder why VGC did not let you look at past data this easily.

DS has so far this year dissapointed in difference to the PsP. (Not really, 67 % isn't exactly bad, but bad compared to 74% the year before)

Wii had 50.87 % market share last year, interesting, I thought it was like 46 % or something.

DS phat almost tied with PsP... 2005 = 54 % DS and 46 % Psp...

Are you sure that X360 was that close to Ps3 in 07? I had a feeling the difference was bigger. If you look at it, Ps3 lost 3 months Europe there, so in a way, it actually sold better...

Great job! This is some of the best data I've seen here. Really easy to view and everything. Is it possible to add overall software? Because that would really be comparable to hardware in a great way here, I think.

Anyway! Superb work!

The numbers are pure raw data, the percentages direct extrapolations from that. Any issues you have with the numbers pretty much should be directed at VG Chartz, as they're the source for them. And the numbers in the first half of the Market Share section tell you the percentage of systems sold that year were that particular system; the second number is the overall market share.
