Onviously every media format will be superceded at some point in time. What you need to look at is longevity. In that respect:
- 8 track was a poor choice over cassette
- Beta was a poor choice over VHS
- LD (and CED) were poor choices over DVD
- HD-DVD will likely be a poor choice over Blue-Ray
- Cassettes were smaller, had much better quality, and were much more reliable that 8 tracks. Cassettes were the portable hi-fi medium of choice during high school (70's-80's), and my 2002 Toyota came with a cassette deck (and CD changer) as standard. That's a good 20 years, maybe 30.
- While DVD's quickly superceded VHS for playback quality, unless you have a DVR, it's still the best way to time-shift record programs. (I know there are VHS-DVD recorder machines out there, but do people use them to say record CSI weekly?). For better or worse I still have a lot of VHS tables, mostly irreplaceable material.
- (12") albums obviously have been superceded by CD's, but I wouldn't call anyone who has a significant album collection "not a visionary". They were around forever, and worked pretty well. Going from analog vinyl to digital (plastic?) was a logical progression. I'm sure almost all of us replaced our most popular albums with CD versions.
- The Pioneer LaserDisc, and then the RCA videodisc (actually used a stylus like an album!) one could say were stopgap measures, filling that void for better video quality that VHS (prerecorded only) before DVD's were introduced. I'd assume at some point the developers of DVD's looked at the LaserDisc, and asked, "How can we make this smaller and better?"
- I can't feel sorry for anyone who bought HD-DVD. It came out basically at the same time as Blue Ray, and it seemed like from the beginning it was always "this is another VHS-Beta war." It was a gamble to invest in either before the market resolved itself to one format.
- One could be tempted to lump in "Sirius vs XM" in this comparison, but (from what I know) I don't think there competition is (was) based so much on technical differences, but rather content. I think the majority of customers are ones that have satellite radios in their cars. I didn't "pick XM" as my provider; rather I bought an Acura, which includes an XM radio as standard. If I bought a Mazda, it would have been Sirius. It's interesting that despite the companies merging, I haven't heard any talk of just having ONE satellite transmission. Instead I think any cost savings is likely the result of combining programming, and multiplexing it on both services (already done with a lot of their channels now).
