With today there isnt a definte line in where art can be drawn. I think i mentioned about this in the Wii thread with that Spores guy.
For me art dies when you start to mass produce it then its not longer art but a product. I dont considered video games art nor music or movies. However if a company had made one game and didnt sell the game then i think theres a statement to it and that could be considered art.
*edit* I talked with a friend and art needs a statement or public reaction to it. The mona lisa can be used for example. Beatuiful painting techniques but its a horrible painting on other terms. Its a portrait, a bad portrait on those terms as well. The background doesnt have depth and really cheesy. What makes that piece what it is, is the publicity. Every time Lisa gets stolen or theres cultural reference the price goes up. In fact most of those classical paintings arent Art. True art probably started with Manet with his The Luncheon on the Grass Or even Rodin and the Bronze age. The reaction, the scandel of art thats what made it art.
