Sound recording and the movie camera were among the greatest inventions of Thomas Edison. They were later united when “talkies” were developed, and they are still used together in video recordings. This unification is one reason for the popularity of movies and video. With the rapid advances in computers in the 1980s and 1990s came multimedia applications, where pictures and sound are combined in the same file. Since such files tend to be large, compressing them became a natural application.
