Music video research

A music video is a short film or video that accompanies a complete piece of music, most commonly a song. Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. Although the origins of music videos go back much further, they came into their own in the 1980s, when MTV's format was based around them. The term "music video" first came into popular usage in the early 1980s. Prior to then, such clips were described by various terms including "promotional films" or "promotional clips".
Music videos use a range of styles of filmmaking, including animation, live action filming, documentaries, and non-narrative approaches such as abstract film. Some music videos blend different styles, such as animation and live action.

influential TV shows- Top of the Pops
In the UK the importance of Top of the Pops to promote a single created an environment of innovation and competition amongst bands and record labels as the show's producers placed strict limits on the number of videos it would use. Therefore a good video would increase a song's sales as viewers hoped to see it again the following week. David Bowie scored his first UK number one in nearly a decade thanks to director David Mallet's eye-catching promo for "Ashes to Ashes". Another act to succeed from this tactic was Madness, who shot on 16 mm and 35 mm short micro-comedic films.
Top of the Pops was censorous in its approach to video content, so another method was for an act to produce a promo that would be banned or edited. It would then use the resulting public controversy to promote the release. Early examples of this tactic were Duran Duran's "Girls on Film" and Frankie Goes to Hollywood with "Relax", directed by Bernard Rose.
The Chart Show
Another important development in music videos was the launch of The Chart Show on the UK's Channel 4 in 1986. This was a program which consisted entirely of music videos (the only outlet many videos had on British TV at the time), without presenters. Instead, the videos were linked by then state of the art computer graphics. The show moved to ITV in 1989, and was axed in 1998. By this time the program's use had largely been supplanted by satellite and cable music channels with increasing numbers of people having access to such channels, and the launch of Digital Television occurring around the same time (Ironically, digital television would lead to the rebirth of The Chart Show in 2002 as a digital music channel, Chart Show TV).

Censorship
As the concept and medium of a music video is a form of artistic expression, artists have been on many occasions censored if their content is deemed offensive. What may be considered offensive will differ in countries due to censorship laws and local customs and ethics. In most cases, the record label will provide and distribute videos edited or provide both censored and uncensored videos for an artist. In some cases, it has been known for music videos to be banned in their entirety as they have been deemed far too offensive to be broadcast.
