Toys and games have changed significantly over time. Early toys were often made by hand from natural materials like wood, clay, and cloth. Teddy bears, the first of which was made in 1902, were also initially handmade. Dolls transitioned from materials like wood and clay to plastic starting in the 1950s as factories began mass producing toys. Over time, toys have gained technology like electric motors and screens. New toys are made of synthetic materials through mass production and must meet safety standards. While materials and manufacture have modernized, some classic toys like teddy bears remain popular today.
