Is Graphic Design Art?

I think this is a rather simple question to answer. Yes, of course it is by it's very definition:

The art or profession of visual communication that combines images, words, and ideas to convey information to an audience.

I didn't even know this was an issue until I went to is graphic design art.com. A site where anyone can vote if Graphic Design is art or not. Apparently so far there is large percentage of people who think it is not. Why they think that is is beyond me. If you truly think Graphic Design is not art, and you have viable reasons for thinking so, please leave them in the comments below.

UPDATE: I have found a very good article that contends that Graphic Design is not art. Although very well written, I believe the article should have been titled Graphic Designers are not Artists. There is a big difference between the two. When you say Graphic Design is not art, you are implying that the finished visual works of designers should not be considered art, but it is just a design, like it has less value, importance, or required skill to execute. Designers use the very same elements as Artists do: line, shape, value, texture, and color. So my question is:

If Graphic Design should not be called art, then what do I call it?

And why stop with Graphic Design? Should we also question whether Architecture, Music, Literature, or Dance is art? Art is a term that is all encompassing for many fields and applies to more than just Artists in the traditional sense (Fine Art). It is a general term as should be treated as such. What I am saying is be specific about what you're talking about because there are literally hundreds of art fields and professions.

I don't know why people like to devalue the work of Graphic Designers, but it needs to end. I've never heard anyone say it was just a dance.

I leave you with this simple definition of art: the quality, production, expression, or realm, according to aesthetic principles, of what is beautiful, appealing, or of more than ordinary significance.

UPDATE: Josh at Cubicle Ninjas has put it best

"Personally, I think you need to define art before you can say they aren't artists. Art can have many far and short definitions, and I think people are reacting to your blanket accusation. But it sounds like you mean "People who create things for visual beauty and personal satisfaction", and by that definition we can all agree that designers aren't artists. Though I do feel there is art within graphic design."
