As for the HD DVD/Blu-Ray War, I pretty much gave a similar argument in the CAGCast #30 topic (It was an answer to the claim that the PS2 was the major factor in DVDs' success). DVDs were a noticably huge leap forward from the VHS and LD formats, and Wal-Mart's support of DVDs brought it to the attention of the mainstream consumers. HD DVDs and Blu-ray have yet to show any neat features that makes them distinctively different than DVDs, other than more storage space.

"
By the spring of 1999 the price of a DVD player had dropped below $300 US. At that point Wal-Mart began to offer DVD players for sale, but DVDs represented only a small part of their video inventory; VHS tapes of films made up the remainder. Wal-Mart's competitors followed suit, and DVDs began to increase in popularity with American consumers.
DVD rentals first topped those of VHS during the week of June 15, 2003 (27.7 M rentals DVD vs. 27.3 M rentals VHS). Major U.S. retailers Circuit City and Best Buy stopped selling VHS tapes in 2002 and 2003, respectively."
The way I see it, there were three major factors in the success of DVDs:
1. The Wal-Mart Effect: Described above; Wal-Mart started to sell DVDs, competitors followed suit; consumers took notice.
2. TV on DVD: Seriously, putting entire seasons of TV shows on DVDs was one of the best things to happen to the format, since people with VHS were stuck with shelves of videos that contained 2 or 3 episodes each. This established a major advantage of DVDs. Heck, I have a strong feeling that a good chunk of people who bought The Simpsons Season 1 box set bought their first DVD player with it.
3. Bonus Features:
C'mon, you'd be lying if you didn't think it was neat to browse through the menu and look through the special features that were in your first DVD, your friend's/family member's DVDs, or the DVDs on display at your local store. It was something that was impossible to do on VHS, and the features made the DVD version of movies seem like a better value.
In short, DVDs gave consumers some pretty convincing reasons to switch from VHS, and Wal-Mart helped introduce these reasons into the mainstream. If either HD DVD or Blu-Ray wants to even start the war, then they need to give reasons to switch from DVDs. Unfortunately, it will be tough to make the major improvements that are comparable to the advantages that DVDs had over VHS. I mean, you have 15-23.3GB of space, so what are ya' gonna do with it, Movie Companies?
As for who would win the HD DVD/Blu-Ray, I agree with Wombat that the mainstream buyer will go for HD DVD because of the name (And possibly the lower price; $499
