The "International Series" refers to a collection of events or competitions that take place across different countries, often involving sports, music, or cultural exchanges. These series aim to promote global participation and foster international relationships, allowing participants to showcase their talents on a worldwide stage. In the context of sports, the NFL International Series is a notable example, featuring American football games played outside the United States. This initiative helps expand the popularity of the sport globally, attracting fans from various nations and providing a unique experience for both players and spectators.
