The ceremonies have evolved over the centuries. Ancient Games incorporated ceremonies to mark the beginning and ending of each successive game. There are similarities and differences between the ancient Olympic ceremonies and their modern counterparts. While the presentation of the Games has evolved with improvements in technology and the desire of the host nations to showcase their own artistic expression, the basic events of each ceremony have remained unchanged. The presentation of the Opening and Closing Ceremonies continue to increase in scope, scale, and expense with each successive celebration of the Games, but they are still steeped in tradition. The 2028 Los Angeles Olympics organisers propose that the opening and closing ceremonies will each, for the first time, be staged across two stadiums.
