MLB Gives Fans Ability to Cheer — or Boo — Virtually During World Series

When the 2020 MLB season began in July with empty stands, the league still managed to bring its homebound fans into the ballpark to cheer — or boo — during games. 
MLB’s “Cheer at the Ballpark” feature resonated with baseball fans so much, the league has decided to incorporate it into this year’s World Series. 
The league launched “Cheer at the Ballpark” ahead of Opening Day on July 23 across the MLB.com website, Gameday app and various social media links. It allows fans to engage with their team’s games by alerting scoreboard operators at ballparks about their reactions. The operators receive a live interface reflecting fans’ thoughts, enabling them to adjust the type of artificial fan noise inserted into the relatively empty stadiums.
