Toymaker Mattel bills Hello Barbie as the world's first "interactive doll" due to its ability to record children's playtime conversations and respond to them, once the audio is transmitted over WiFi to a cloud server. In a demo video, a Mattel presenter at the 2015 Toy Fair in New York says the new doll fulfills the top request that Mattel receives from girls: to have a two-way dialogue. "They want to have a conversation with Barbie," she said, adding that the new toy will be "the very first fashion doll that has continuous learning, so that she can have a unique relationship with each girl." Susan Linn, the executive director of Campaign for a Commercial-Free Childhood, has written a statement in which she says how the product is seriously creepy and creates a host of dangers for children and families. She asks people to join her in a petition under the proposal of Mattel discontinuing the toy.
