To Promote a new Release:
One of the main reasons for bringing out a new music video is to promote and advertise an artists new single. This is largly helped by the internet in recent years and the invention of websites such as Youtube and other streaming sites. This way of advertising a new single means that the artist can control the release time of the video and try to build up the fans anticipation which in turn will increase the overall sales of the single. The video being accessible online also means that it can be viewed by people all over the world increasing their popularity and getting them noticed in the music world. This is also a free way to display videos meaning that even a person on a very low budget can put their song on the website to be heard and enjoyed. Also with the artist able to control the release whilst simultaneously using other types of media to promote their video they are able to make just the release of the video an event in itself, also increasing the number of sales.

This statistic shows that a relatively unknown british band is fairly popular in most of North America and Australia
Creating a Visual Representation of the Artist:
The way in which the video is shot, the props and costumes that are used and the location and actors all help to communicate the style, energy and genre of the song. Not having lots of cuts in a video can help to emphasis the slow pace of the song and it gives the audience time to appreciate the lyrics and imagery in the video. Also the style and amount of special effects can show how the artist wants to appear to the audience and helps to display that artists brand. Having a music video also allows the audience to see the artist while not actually performing this helps to make the artist seem more accessible to the audience as they are looking at a person and not just a singer/performer. With the amount of special effects and techniques available now artists are ably to reinvent themselves to maintain their popularity and keep up sales of their songs. This means that artists can extend their career over a far greater period of time allowing them to change their style of singing and attempt new genres which will again increase the sales of their music.

Extending the Playability & Creating additional Income:
A music video can be shown on a music channel for a far longer period than the single would get air play on the radio, this helps to promote the artist over a longer period of time. This keeps the artist in the public eye for longer increasing their fan base and therefore their sales.As the video is repeated many times on music channels the artist also gets added income from the royalties that have to be payed to them. Also when the music video is on a streaming site the adverts that appear whilst their video is being played provide additional income, another way in which a music video provides an income for the artist is by releasing a DVD with a collection of music videos.

Creating Synergy with other Media Sectors:
An artists music video can contain references and tie-ins to other businesses in order to create links between the two and increase awareness and popularity. This is done mainly when a song is played in a movie and the music video incorporates scenes from the movie. This is when an artist is asked to produce a soundtrack for a movie and when the artist makes a music video for that song they incorporate parts of the movie as well. This also allows the artist to explore new sectors and expand their career into other media forms e.g. acting.
This Paramore video shows scenes from the first Twilight movie in which their sone "Decode" is featured.
To be Art in Their Own Right:
Some videos are produced not just to add a visual element to the song but also to act as a piece of art that deserves the audiences attention separate to the song itself. When a video is produced in this way it intrigues the audience and encourages them to think about what connection the song has to the video if any. This also allows the audience to gain some insight into how the artist visualises the song themselves and what they were thinking and feeling when they wrote the song. An example of an artistic music video would be when two or more music videos create and follow story line.
These two videos by Green Day show a continuing story line of the groups journey in a car and when the car breaks down.
