The term "Release Year" refers to the specific year when a product, such as a movie, video game, or album, is made available to the public. This date is significant as it marks the official launch of the item, allowing consumers to purchase or access it. For example, the movie "Avatar" was released in 2009, making that year important for its box office performance and cultural impact. Release years are often used to categorize and compare different works within the same medium. They help audiences track trends, understand historical context, and appreciate the evolution of entertainment over time. For instance, knowing that the video game "The Legend of Zelda: Ocarina of Time" was released in 1998 allows fans to recognize its influence on later games.
