A while back. Here's the top Google result for it:

"the most immediately obvious difference between the two formats was the recording length. Standard Betamax tapes lasted 60 minutes — not long enough to record a movie. Conversely, the 3-hour VHS tapes were perfect for recording television programmes and movies. Sony did adapt and offer various solutions for longer recording, but it was too late. The issue of recording time is often cited as the most defining factor in the war."

Thats why VHS won

on many websites that goes through history as why VHS won none of them say any thing about porn

Personally, I don't care, I would rather sit on the fence until a winner comes out completely, but if I must choose, then HD-DVD. I don't see how blu ray will win, mainly for the fact that sony has decreed that the adult industry will not be allowed to put their content on blu ray, so they will go hd-dvd (sound familiar? betamax v vhs). Plus I don't understand the arguement that ps3 will carry the blu ray. PS3 has blu ray, so what? The PS3 launch was a disaster for Sony, there are more PS3s in stores than in homes. I can't go to a Best Buy or any other electronics retailer and not be hassled about being reminded how they have PS3s in stock. "We do have PS3s, please buy one." I think the stores are probably gouging at their own eyes about the PS3. Its harder to find a Wii, which I wouldn't mind having, but finding a Wii is getting easier.

Now back to topic. Personally, I have no need for either. The current DVD format suits me just fine, plus, most movies that I have seen on either hd-dvd or blu ray, ARE STILL ENCODED IN MPEG-2, not the new MPEG4 which was so promised by both formats, and really I don't have the equipment to 'enjoy' the higher res, oh and lets not forget the new restrictions. I am sure it will be harder to play either format in an open source enviornment, and whats all this crap I hear about HDCP, and downgrading resolution if I don't have the right HDMI connections, fsck that. Until the DVD format itself gets phased out by ONE format only, hd-dvd or blu-ray, then I will be switching, but wait, I also hear that in a few years, disc media will become irrelavent, due to movie downloads, and higher and higher storage capacity of solid state media (compact flash, sd, etc).

HD-DVD i think will win because it is cheaper. It is cheaper to buy 2 dvd's than it is to buy a single dvd-/+DL disk, and it will most likely be cheap to buy 2 hd-dvds than a blu-ray disk. I cant imagine porn having the decding factor this time round, because from what i have read HD porn looks shit, and most people will be more than happy with SD porn.
Cost will be the deciding factor, along with marketing of course, and as of now hd-dvd is cheaper to buy, cheaper to burn on, and cheaper to watch.
The 15gigs that is a hd-dvd disk, is plenty enough for a full HD movie, and extras and even if it is not, nobody realy complains when u get dvd extras on a seperate disk, and nobody will mind if u get HD extras on a seperate disk.
Cost over quality; betamax better, vhs cheaper. mini disk better, cd cheaper. It is going to happen again. The only people that can stop HD-DVD winning is the HD-DVD camp.

I still want Blu-Ray to win but I think you might be right. On the same note the HD-DVD players are also half the price of the current Blu-Ray players from Sony. $500 vs $1000? Seems to be obvious... also makes a PS3 suddenly look like a bargain!

Because HD-DVD copy protection has already been cracked.

@Someone: How is the Playstation great? All it's been doing is pushing Sony tech on the consumer. Plus, alot of the products turned out reasonably crappy.

I want the one with less DRM. Either DHVD (Holographics) or PaperCDs.

Doesn't matter if Blue-Ray is Sony and HD-DVD is MS, both are DRM infested sacks of crap, so I'm not voting for either.

If I ever purchase a blue-ray or hd-dvd drive it will be the $50 no named brand made in china.
Who really gives a damn about "premium content" on PCs?

Blu-Ray has a higher capacity and so might be better for backups. Also, the disks have a coating which is supposed to protect the discs against scratching.

However, for Movies, mastering a Blu-Ray disk is 2 orders of magnitude more expensive, so I think that this will result in most movies being put out in DVD-HD rather than Blu-Ray.

I talked to an employee at Vid-Cycle. He said that they don't know how they can clean Blu-Ray disks. The machine they use to clean and refurbish DVDs will strip off the coating from a Blu-Ray disk and render them unusable.

From what I remember, the Porn industry preference was influential when you could just buy players. It was after tuners and recording capabilities were added that sales of VTRs took off.

Also, JVC (Japanese Victor Corporation) had a service network (RCA) in the US which made it easier to get equipment serviced under warranty.

Blu-Ray discs have scratch protection?

Last I checked Blu-Ray could be killed by simple scratches, and HDDVD was the more resistant one.

Regardless, I still love the paper CDs. I can cut them up with my schizzor!

guy's I have found a new news on the porn thing

"Surviving Clean Living

While Sony is keeping it at arm's length, the Blu-ray Disk Assn. (BDA), of which Sony, as it happens, is a member, takes a more liberal view. "The BDA welcomes the participation of all companies interested in using and supporting the format," it says. In late March, Vivid Entertainment, another producer of adult content, plans to release Debbie Does Dallas…Again on Blu-Ray and HD-DVD. Vivid hasn't said which Blu-ray company it's working with.

Adult-oriented content has also appeared on Sony's PlayStation Portable handheld game consoles. In 2005 in Japan, two companies, h.m.p and GLAY'z, released adult titles, including The Nurse of a Big Breast, using the UMD disk format.

Perhaps more important, some analysts question the extent to which porn was responsible for VHS crushing Betamax in the first place. While VHS undoubtedly played a huge role in taking adult entertainment to a wider audience, other—admittedly more mundane—factors may have been important in establishing the dominance of VHS.
The PlayStation Effect

For example, when Betamax first appeared, cassettes only lasted an hour. VHS tapes first lasted two hours and later, four hours. Despite Betamax offering superior viewing quality, VHS quickly became the established standard in most homes and rental stores. There are also differences between Betamax versus VHS in the 1980s and Blu-Ray vs. HD-DVD today. Betamax and VHS were effectively battling to dominate a new market, but today's high-definition disks are essentially new generation of an existing market.

Whether fans of adult movies prefer cheaper DVDs or high-definition quality remains to be seen, but it isn't the case that these movies will necessarily decide the fate of Blu-ray versus HD-DVD. "It is true that content determines the winner, but I'm just not sure that adult is the defining factor," says David Gibson, an analyst at Macquarie Securities in Tokyo.

Then there's the role of the PlayStation3, which includes a Blu-ray player. Despite several missteps (see BusinessWeek.com, 11/14/06, "Sony's PS3 Issues Threaten Revival"), the PS3 is selling well and already responsible for putting far more Blu-ray players in people's homes than there are HD-DVD players. "I did read all the HD-DVD excitement, but I think they sold 60,000 players, and we actually put out a million Blu-ray players," Sony chief Howard Stringer told Cnet.com on Jan. 22.
