A "Launch Trailer" is a promotional video created to generate excitement and interest for a new product, game, or movie. It typically showcases key features, highlights, and visuals to attract potential customers or audiences. Launch trailers are often released shortly before the official launch date to maximize visibility and engagement. These trailers are commonly used in the entertainment industry, particularly for video games like Call of Duty or movies such as Avengers: Endgame. They serve as a marketing tool to convey the essence of the product and encourage viewers to make a purchase or attend a screening.
