One of the causes of decline was new generations of video game consoles and personal computers that sapped interest from arcades. Since the 2000s, arcade games have taken different routes globally. In the United States, arcades have become niche markets as they compete with the home console market, and they adapted other business models, such as providing other entertainment options or adding prize redemptions. In Japan, some arcades continue to survive in the early 21st century, with games like Dance Dance Revolution and The House of the Dead tailored to experiences that players cannot easily have at home.

Elements from games such as Space Invaders, Pac-Man, Donkey Kong, Frogger, and Centipede are still recognized in today's popular culture, and new entries in the franchises for some golden age games continued to be released decades later. Pac-Man and Dragon's Lair joined Pong for permanent display at the Smithsonian in Washington, D.C. for their cultural impact in the United States. No other video game has been inducted since.
