Did video kill the radio star?

The purpose of music videos and radio stations are to promote the band and their song/s. This will help to increase the sales of their songs so they can climb up the charts and become more successful. However, music videos do one other thing that radio cannot do - they can create a visual image of the band if people haven't seen them live.

Today, music videos are very important on promoting the band. Particularly in recent years where music videos for pop songs seem to have a trope of having big production story lines in them. For example, Lady GaGa's "Telephone" is around 9 minutes long for a 3 minute long song just because of the development of the storyline.

Does this mean though that in today's society bands and music artists are reliant on their image? In pop music I believe so. Lady GaGa being the obvious choose for her controversial outfits and music videos and I hardly doubt that Justin Bieber would have as many fan girls screaming over him if he was portrayed as ugly in the media. But are music artists reliant on their image in other genres of music? Again I think this seems to be case. I don't they're completely reliant upon it but it does seems to make an impact.

For example, 10 or 20 years ago, rock bands wouldn't have seemed to have cared about there image. Now though, it seems that they are when it comes to how they look or what their music videos look like. Take My Chemical Romance's video for "Sing". They have gone along with the trope of having a big production storyline in it. And again, you will hear fan girls discussing about the appearance of the members of these rock bands.

So in my opinion, music videos do play a major part in promoting a band and their song. In fact more than radio now. However, music videos mainly promote the band's image. The main component of all of this, as I see it, is the actual song (although this could be debatable these days). So although radio isn't as significant as music videos are, they are still vital in promoting songs. Hence why I think music videos have not yet killed the radio star.
