For a very brief time Britney Spears was referred to as a living breathing Barbie doll come to life by Mtv. This was before she started getting edgy, chubby, and overly sexual on stage, and her doll line was discontinued.
After the late 90s teen pop singing dolls disappeared until around 2007. This is when Disney released those High School Musical, and Hannah Montana dolls. Taylor Swift, Justin Bieber, and One Direction dolls became a thing, and there were also a few other dolls based off of Disney Channel / Nickelodeon stars.
The fact that the hit Disney channel show Girl Meets World didn't have any dolls created to help promote the show kinda cements that this fade is dead once again.
