The year 2020 witnessed numerous sports events being conducted without live audiences due to the global COVID-19 pandemic. This unprecedented situation led to empty stadiums and arenas, creating a unique atmosphere for both athletes and viewers worldwide. 
Major events like the Tokyo 2020 Olympics （held in 2021）, UEFA Euro 2020, and various professional leagues including NBA, Premier League, and IPL adapted to this new normal by implementing strict health protocols and playing behind closed doors.
While the absence of cheering fans changed the dynamics of competition, these measures were crucial for ensuring the safety of all participants and allowing sports to continue during challenging times. |
