A "Highlight Reel" is a compilation of the most exciting or significant moments from a longer event, such as a sports game, concert, or film. It showcases key plays, performances, or scenes that capture the essence of the experience, allowing viewers to quickly grasp the highlights without watching the entire event. Highlight reels are commonly used in sports, where they feature impressive goals, tackles, or plays from athletes like LeBron James or Lionel Messi. They are also popular in entertainment, summarizing key moments from movies or shows, making it easier for audiences to enjoy the best parts.
