The one that will come to the top will be the one that:
1) Caused the most FUD
2)Spent a lot of $ advertising
3) Bought out or smashed it' competition.
It will not win because of its:
1) Superior technical solution.
2) Widespread acclaim.
3) Lifetime Cost savings to the end user.(Cheap initial cost is not always the cheapest to use)
4) Works best for ALL conditions
Examples:
NTSC vs PAL (old TV signal standard) ((DTV has a way better Picture but fails TOTALY in weak signal (emergency?) conditions)
VHS vs Betamax
SQ/QS vs CD4 vs Discrete Tape (Quad sound, the predecessor to DTS/Dolby Surround)
Videotape vs Laserdisc (Play only) (replaced by DVD)
M$ Windows vs MAC O/S (Linux was not around then)
A Dominant solution is not always the best solution.
One Size rarely Fits All
