Over the last 10 years, girls on YouTube have been creating stop-motion
videos with their American Girl dolls. Many of these girls began producing videos
when they were tweens and have continued participating in the American Girl
YouTube (AGTube) community into their late adolescence and early adulthood.
In this article, I explore the intertextuality of tween girl culture as it is performed
and reflected on by teen (13 to 18) and young adult (19 to 24) girls in their online
doll videos. Through an examination of their AGTube channels, I show how girl
producers negotiate their experiences and desires as teens and young adults within
the tween culture of American Girl. I argue that AGTube functions as an audience-
generated paratext of American Girl, and demonstrate how teen and young
adult girls interact with and challenge the marketplace boundaries of tween girl
culture in digital spaces.
