Previews are short segments or clips that provide a sneak peek of upcoming movies, TV shows, video games, or other media. They are designed to generate interest and excitement by showcasing key scenes, characters, or gameplay elements. Previews can be found in various formats, including trailers, teasers, and promotional videos. In the film industry, previews often appear before a movie in theaters or on streaming platforms. They help audiences decide what to watch next and can influence box office performance. Similarly, video game previews allow players to see gameplay mechanics and storylines before release, helping them make informed purchasing decisions.
