This suggests to me that Hulu and such may not work for the big entertainment companies or for those who earn their living off of reuse:
The music industry has a new Internet problem. A decade ago, the major record labels began to worry about online piracy, in which people illegally swapped music over peer-to-peer networks like Napster (BBY) and later LimeWire. Partly in response to the piracy threat and partly due to sliding CD sales, music companies began to experiment with licensing their records to new online services.
...Researchers and industry consultants say online music sites are being used by a growing number of listeners as a substitute for purchasing music, rather than serving as a catalyst for more purchases...
Overall music sales have continued their years-long slide. Total industry sales were about $10 billion last year, down from $14 billion in 2000...Revenues from digital download services like Apple iTunes (AAPL) and Amazon MP3 (AMZN) are still growing strong, but they're not generating enough revenue to make up for the sharp decline in CD sales. Overall spending on music is forecast to shrink 4% through 2013, according to a recent report by Forrester Research (FORR).
