The Arcade Fire has released a music "video" that relies heavily on the internet and the watchers personal history to be completed. "The Wilderness Downtown" is an interactive website, developing a music video based on the address where the viewer grew up, and map data to complete itself. Part way through the video, user interaction is used to generate art that may be used for promotional material for the band, or during a live performance
This is the first time I've seen a music video that could not actually be viewed without the internet or computer. The concept just wouldn't work on a normal T.V. Internet killed the video star indeed.
Works best (requires?) with Google Chrome
