The PPM was originally developed for use in AM radio broadcasting networks in the 1930s, independently in both Germany and the United Kingdom, as a superior alternative to earlier types of meter which were not much use for monitoring peak audio levels. These were both quasi-peak meters with some features in common but otherwise substantially different.
