Entertaiment is a big part of life. It can be something you do privately, like playing games or watching TV, or shared with others, such as going to movies or concerts. It can be a performance, such as a theatre show or concert, or it can be an activity staged for a global audience, such as a sports event. Entertainment evolves over time as new cultures and technologies emerge. However, it can also be a way of reinterpreting old traditions in new ways. This is reflected in how many familiar forms of entertainment can be seen as cultural touchstones that persist across decades and even centuries.
