I agree with Samsung on this. Blu-ray will most likely not see the same kind of life span as DVD. The reasoning behind this is that there were far greater differences/advantages with DVD compared to VHS, than there is between DVD and Blu-ray. In other words it will take much longer for Blu-ray to capture the market, than it took DVD.
I believe we will see downloadable content take over the market within a few years - perhaps even before Blu-ray has replaced DVD as market leader. It's inevtiable.
- All Blu-ray players will play all DVDs and the playback will be upscaled to 720p.
- The migration from VHS to DVD was slowed because people had to discard their VHS libraries in favor of DVDs or they had to retain their VCRs for VHS playback.
- The resolution improvement from VHS (240x480) to DVD (720x480) is much less than the improvement from DVD (720x480) to Blu-ray (1920x1080).
Compared to VHS
DVDs didn't need to be rewound
DVDs were smaller and lighter
DVD's were less prone to losing quality over time (digital not analogue)
DVD's could have 'special features', and these could be navigated through
DVD's could be paused without damaging them
DVD's could have bookmarks placed in them, both by the studio and the consumer
DVD's make excellent coasters
Blu Ray > DVD >>>>>>>>>>>>>> Betamax>VHS
