Mashups combine information from various sources into a single source. The rise of the digital age has caused mashups to become commonplace on the Internet. Mashups come together into various formats, including: maps, websites, music, dashboards, etc. Use of visualization conveys information available in most visual mashups. Audible mashups are typically made up of various recorded songs.


Cartography, or mapmaking, is a long practiced art.[1][2] Mashups are used as a way to enhance maps and the information they convey. Adding geospatial and geographic information to maps creat a two dimensional view of the location.[3] Additional information, such as, statistics gained from census and other media resources are added to further enhance the information provided to the user.



Website mashups allow the features from various websites to merge the information provided from each site to create new information. Popular websites that provide or hold data are especially utilized, new mashup websites providing interesting ways to offer the information. These mashups can provide convenience to users, provide information in a more simplified format, or just be something for fun.



Music mashups are the most contentious form of mashup. Issues of copyright are most prevalent with these mashups and the recording studios are very proactive in protecting their profits. Sampling, using a sample of a soundrecording from one song and using it in another, has been occuring for decades. Mashups are new to the scene, due to technology and the Internet, but are pretty much the same concept. There have been a number of lawsuits against artists using samples of soundrecordings from other bands for their own music.[4] Most recently there is a lawsuit against rap artist Snoop Dogg for his supposed sampling of work by Michael Henderson, jazz musician.[5] With regards to mashups, recording label EMI has sent a cease and desist letter for a mashup of Nirvana and Lady Gaga songs.[6] In 2004, EMI attempted to halt the distribution of a mashup, The Grey Album, of the Beatles' White Album and Jay-Z's Black Album.[7]



Dashboards are a form of mashups that display in a visualization multiple information sources on a single platform. The information is taken from various locations, usually internal, and displayed in a format that allows the information to be viewed and understood simply.
