"Bestselling" refers to products, typically books, that achieve high sales figures within a specific time frame. This status is often determined by sales rankings from retailers or industry organizations, such as The New York Times or Amazon. Bestsellers can vary by genre, format, and market, reflecting consumer preferences and trends. The term can also apply to other items, including music albums, movies, and consumer goods. A bestselling product often indicates popularity and can influence purchasing decisions, as consumers may perceive these items as more desirable or of higher quality due to their success in sales.
