Children

Children's entertainment is centred on play and is significant for their growth. It often mimics adult activities, such as watching performances (on television); prepares them for adult responsibilities, such as child rearing or social interaction (through dolls, pets and group games); or develops skills such as motor skills (such as a game of marbles), needed for sports and music. In the modern day, it often involves sedentary engagement with television or tablet computer.

Entertainment is also provided to children or taught to them by adults. A children's entertainer or performer is a professional whose job it is to entertain children. The term can be used to describe a children's musician or television presenter, but encompasses a wide range of specializations, including magicians, costumed performers, puppeteers and party princesses. Many activities that appeal to children such as puppets, clowns, pantomimes and cartoons are also enjoyed by adults.

Children have always played games. It is accepted that as well as being entertaining, playing games helps children's development. One of the most famous visual accounts of children's games is a painting by Pieter Bruegel the Elder called Children's Games, painted in 1560. It depicts children playing a range of games that presumably were typical of the time. Many of these games, such as marbles, hide-and-seek, blowing soap bubbles and piggyback riding continue to be played.

Most forms of entertainment can be or are modified to suit children's needs and interests. During the 20th century, starting with the often criticised but nonetheless important work of G. Stanley Hall, who "promoted the link between the study of development and the 'new' laboratory psychology", and especially with the work of Jean Piaget, who "saw cognitive development as being analogous to biological development", it became understood that the psychological development of children occurs in stages and that their capacities differ from adults. Hence, stories and activities, whether in books, film, or video games were developed specifically for child audiences. Countries have responded to the special needs of children and the rise of digital entertainment by developing systems such as television content rating systems, to guide the public and the entertainment industry.

In the 21st century, as with adult products, much entertainment is available for children on the internet for private use. This constitutes a significant change from earlier times. The amount of time expended by children indoors on screen-based entertainment and the "remarkable collapse of children's engagement with nature" has drawn criticism for its negative effects on imagination, adult cognition and psychological well-being.
