Link to Google Trends
I commonly see questions about Vocaloid/Hatsune Miku's popularity. And often I see people show a Google trends graph with a "woe unto us!" showing Vocaloid's catastrophic decline. I kept looking at it and thinking "this can't be the whole story." Then I noticed that, by default, when you are logged into Google it only allows you to go back to 2008. However, if you are not logged in it will let you go back all the way to 2004. So I put in Miku's release date of August 31st, 2007. Now the data looks more sensible. To illustrate why this data looks more accurate I overlaid key events at their points in time.
