In technology, a mashup is a Web application that combines data from more than one source into a single integrated tool; an example is the use of cartographic data from Google Maps to add location information to real-estate data from Craigslist , thereby creating a new and distinct web service that was not originally provided by either source. Mashup originally referred to the practice in pop music (notably hip-hop) of producing a new song by mixing two or more existing pieces.
