Quoted from Wikiepedia "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."
They has been a lot of controversy over the censorship of music videos with people asking questions such as "Is that really necessary?". Blurring out a image of a naked person may be needed on day time TV but is it needed to bleep out words such as Gun?
Videos that need censoring can be changed in a few ways.
1. Quite often a video that is too explicit to be show on day time TV may just be moved to be shown on a late night TV slot. This happened with Cher's If I Could Turn Back Time which was banned due to her performing wearing very revealing clothes on a ship full of sailors.
2. Quite often a video and song is changed so it can be shown. Sometimes words are changed such as the song "We are all on drugs" By Weezer where the song was changed to "We are all in love". And sometimes videos are re filmed but a version that won't be censored. Below is the rerecorded version of the song with the original video. If you look closely you can notice that the singing is all out of time with the track.
3. Sometimes the videos are banned all together and the Artist doesn't attempt to re release a video.
- Before when MTV was the only place to watch music videos, if a video you wanted to see was banned they you wouldn't get to see it. These days through the Internet and such websites such as YouTube anyone can watch banned material.
