Mattel accused by health expert of 'stealth marketing' to children by placing free Barbie dolls in schools

• Mattel has been heavily marketing its new Barbie movie.
• Some health experts are angry over a project the firm funded in schools, per The BMJ.
• One criticized the decision to give dolls to UK schools as "stealth marketing."

The new Barbie movie's seemingly unlimited marketing budget has seen multiple brand collaborations, pink burgers, and the construction of a real-life Barbie dream house.

But some experts in the health sector are concerned about how far Barbie maker Mattel's marketing really goes.
