The BarbieGirls Museum
Like the page title suggests, there are links here, links to other interesting BarbieGirls related websites.
A fansite I used to visit, now left completely abandoned.
A blog post about the site's closure with many upset reactions in the comments
A 2009 speculation post from the same blog about whether or not BarbieGirls might close in 2010
A fairly recent Instagram account trying to bring BarbieGirls back
(this shows that there is still interest in the site!)
The abandoned "Bring Back Barbie Girls Campaign" homepage
I am trying to find the archived link to the free download pack of BarbieGirls wallpapers and avatars Mattel gave away when the site closed. That will be put here eventually.
