Digital toys are toys that incorporate some form of interactive digital technology. Examples of digital toys include virtual pets and handheld electronic games. Among the earliest digital toys are Mattel Auto Race and the Little Professor, both released in 1976. The concept of using technology in a way that bridges the digital with the physical world, providing unique interactive experiences for the user has also been referred to as "Phygital."
Certain toys, such as Barbie dolls and toy soldiers, are often perceived as being more acceptable for one gender than the other. The turning point for the addition of gender to toys came about in the 1960s and 1970s. Before 1975, only about two percent of toys were labeled by gender, whereas today on the Disney store's website, considered a dominating global force for toys by researcher Claire Miller, all toys are labeled by gender. The journal Sex Roles began publishing research on this topic in 1975, focusing on the effects of gender in youth. Too, many psychological textbooks began to address this new issue. Along with these publications, researchers also started to challenge the ideas of male and female as being opposites, even going as far as to claim toys which have characteristics of both gender are preferable.
During the Second World War, some new types of toys were created through accidental innovation. After trying to create a replacement for synthetic rubber, the American Earl L. Warrick inadvertently invented "nutty putty" during World War II. Later, Peter Hodgson recognized the potential as a childhood plaything and packaged it as Silly Putty. Similarly, Play-Doh was originally created as a wallpaper cleaner. In 1943 Richard James was experimenting with springs as part of his military research when he saw one come loose and fall to the floor. He was intrigued by the way it flopped around on the floor. He spent two years fine-tuning the design to find the best gauge of steel and coil; the result was the Slinky, which went on to sell in stores throughout the United States.
Having carefully considered the subject of the above discourses, and wondering within myself whether the present times were propitious to a new prince, and whether there were elements that would give an opportunity to a wise and virtuous one to introduce a new order of things which would do honour to him and good to the people of this country, it appears to me that so many things concur to favour a new prince that I never knew a time more fit than the present.
The golden age of toy development was at the turn of the 20th century. Real wages were rising steadily in the Western world, allowing even working-class families to afford toys for their children, and industrial techniques of precision engineering and mass production was able to provide the supply to meet this rising demand. Intellectual emphasis was also increasingly being placed on the importance of a wholesome and happy childhood for the future development of children. William Harbutt, an English painter, invented plasticine in 1897, and in 1900 commercial production of the material as a children's toy began. Frank Hornby was a visionary in toy development and manufacture and was responsible for the invention and production of three of the most popular lines of toys based on engineering principles in the twentieth century: Meccano, Hornby Model Railways and Dinky Toys.
One means of reducing the mismatch between the buyer and receivers' tastes is advance coordination, often undertaken in the form of a wedding registry or Christmas list. Wedding registries in particular are often kept at a single store, which can designate the exact items to be purchased (resulting in matching housewares), and to coordinate purchases so the same gift is not purchased by different guests. One study found that wedding guests who departed from the registry typically did so because they wished to signal a closer relationship to the couple by personalizing a gift, and also found that as a result of not abiding by the recipients' preferences, their gifts were appreciated less often.
One example of the dramatic ways that toys can influence child development involves clay sculpting toys such as Play-Doh and Silly Putty and their home-made counterparts. Mary Ucci, Educational Director of the Child Study Center of Wellesley College, has demonstrated how such toys positively impact the physical development, cognitive development, emotional development, and social development of children.
