The trends are undeniable. Regarding CD's I believe it was as recent as Jan 2013 digital sales exceeded physical sales. This will continue to accelerate until CD's make up a minor percentage where it will stabilize. DVD/BR headed there too and will likely get there in a shorter time frame than CD's did. On demand and digital downloads in home just make it more appealing than buying a DVD/br. There may be segments that retain share like children's for instance.
For people who want to watch a movie one time I agree that streaming or downloading beats out buying a DVD. However, there are still many of us who want to keep a movie to watch more than one time and if we stream or download it we still need to create our own physical copy which means DVD's will still be utilized.
Physical movie rentals shuttered because it was more convenient to stream on demand than drive to the store and/or wait for the mail to arrive with your Netflix selection. But if you want to store your selection you have no other practical choice than DVD.
Flash drives and mobile players have replaced a lot of CD's but if you want full fidelity or want to permanently store your selection you have no other good choice than DVD/CD.
I agree the market has changed but I disagree that either CD's or DVD's are obsolete.
