Is there a bug in the old data? When I click on some of the old charts from blast from the past, or try and jump to the November/December data from 2006, all I get is the most recent chart.

i look at old charts....i requested this last night...until my Tetsuya account got banned....T_T

One thing you might do is have some sort of calendar format where you have links to older dates in a table instead of a drop-down list. The long list can be a bit difficult to scroll through and keep track of where you are at the same time.

Something else that I think would be really cool is if you could look at monthly and yearly historical data also. Of course, that would involve making more pages and adding the data together for those pages. I'm sure you have way too much work on your plate as it is...

Hey ioi. The old data is great. I use it often and sorely miss the NA data. 

i love the old data, maybe more snes, md, sms, nes, atari software would be great, but i know is difficult.

old data is amazing if you are doing some research or tracking sales of s/w.
Vgcharts should continue to host "old data"

I look at them all the time. To me it's fascinating. I just wish all the charts had these blast from the past stuff.

The old data from the Japan dataset is awesome, would love to see how games did in America back in the 90's as well.

For promoting it, I think it would be cool to pick a particular month of a particular year (say January of 1991) and write a review as to why the game's sales numbers turned out like they did. Things like company trends at the time, game character popularity, etc. could be discussed as the reasons for a game's success/failure.
