Postman argues that childhood is disappearing altogether. The distinction between adults and children is disappearing due to media, the internet and TV. in the 19th century, mass literacy occurred, causing an information hierarchy (had to learn to read to access adult information so children couldn’t access this.) Postman believes that information hierarchy is the reason why childhood and adulthood are separate stages. However today children don’t need skills to access adult information, they can get it through media. Therefore childhood is disappearing altogether
