Businesses in the prerecorded entertainment category supply entertainment that has been recorded in advance for customers to watch or listen to at a time of their choosing. This can include films, television programmes, music, comedy, spoken-word recordings and other audio or video content. Material may be offered on physical formats such as CDs, DVDs and Blu-ray discs, or as digital downloads and on-demand access, depending on the business. Typical services include selling or distributing recordings, helping customers find particular titles or formats, and providing information about editions, content and playback compatibility. Some businesses focus on a particular genre, audience or medium, while others offer a broader catalogue. Products may be new, second-hand or collectible, and can include boxed sets, albums, soundtracks and recorded performances.
