I think a lot of people have a hard time understand what a FORMAT WAR is.
A FORMAT WAR is when two rival formats battle it out.
It's not when multiple formats with equal support battle it out.
FORMAT WAR: Beta vs VHS. VHS had more studio (and porn) support. In the end they won.
Not a Format WAR: Cable vs Satelite. These two different formats have for the most part equal support from networks.
FORMAT WAR: DVD-A vs SACD. Neither format caught on and neither format got any real music studio backing. The best selling disc on either format was Pink Floyds Dark Side of the Moon on SACD. Despite that no other Floyd albums ever made it to SACD.
Not a Format WAR: LCD vs Plasma.
FORMAT WAR: HD-DVD vs BD.
If HD-DVD and BD had equal and universal Studio Support it would just be a CE market share battle and consumers would care less and just buy what was best for them.
I personally feel that the "format war" categorization is legitimized by one thing and one thing only: consumer perception.
If consumers worry about "getting stuck with the wrong format", then there's a format war.
If they don't worry then there's no format war.
Consumers worried about "getting stuck with the wrong format" with SACD/DVD-A, Beta/VHS, and now HD DVD/BD. Those are format wars.
The didn't worry about getting stuck with the "wrong format" between CD or Cassette, Laserdisc or VHS, Cable or Satellite TV. Those are not format wars and those formats coexist (probably because they satisfy different market needs).
Of course, the background market reasons that would affect consumer fears may be the context that you're detailing in your comments. And that may be right. But the final litmus test for me is simple: are consumers worried about getting stuck with the wrong format? Yes=Format War. No=No war.
