Age rating a mandatory requirement to marketers of children's apps
Here are examples: a section of children beloved Toy Story video was re-made using dirtiest language and uploaded to youtube - my 2yr old picked up as the thumbnail is still her favorite Woody. Another example-Angry Bird is very popular game that you can download from either iTune or Android Market, but there is no rating for age. Is it a good thing that a toddler having fun being angry and killing pigs? Movies have different ratings. Why apps don't?
