music is not movies. I can download a song in 10 seconds, however it would take me several hours to download an HD movie. Again, this may improve. Also, you must remember that music is cheaper on Itunes most of the time that at the stores, and the quality of the music is not as good. I didn't say movie downloads would never come around, just not anytime soon for many reasons. Quality, download time, DRM issues. Why would I want to buy a movie online for $20.00 when I would then have to spend additional money to store it? Be it additional hard drives, BR-Discs, whatever. Also I would be spending my time putting it on the discs if I chose that route.
Music is a lot easier as it take up relatively little space. A good quality HD movie is going to take up 30-50 GB per movie. 20 movies fills up a $200 1TB hard drive. Plus, who trusts hard drives for long term (5+ years) storage? I would have to spend 20 a piece on a BD disc to store it long term.
I can see all of this happening in the future sometime, but for now, most of the public does not even know how to make a music CD, please don't think the majority of consumers are going to want to learn how to do all this downloading and saving of HD movies. Given the choice, a vast majority of people are going to go buy a product at the store rather than going through all the steps and costs mentioned above. Its just not going to happen.
What about Apple (iTunes) becoming the top music retailer in the US?
While holding a 19% share is VERY good for any retailer, the article points out the next digital download music site Amazon at 6%. Thats 25%. Lets just say the other sites for purchasing digital music combined are at 5%. All together, thats 30% of music sales; 70% of music sales are still traditional. Which I admit, I thought it would be still higher than that. But again, thats Music, not movies.
