leaglebob… Unfortunately your assumptions for why VHS won the standard war for tapes has nothing to do with length… it’s actually simpler than you think and might find a bit shocking. Firstly, let it be known that Beta had better video & sound quality, in fact larger betamax tapes are STILL used in the TV industry. Secondly, before VHS/Beta was created you ONLY watched movies in the theater, and people were use to that idea. The biggest fueling need for video at home was to get what you can easily get in the theater, adult entertainment. Sony specifically refused to let adult companies get Beta tapes. Because of this, virtually every adult male bought a VHS machine because if you wanted adult entertainment, you HAD to buy a VHS machine. Well if you didn’t own a a Beta Machine then obviously you’ll buy the VHS version of your movie. My point is, the adult entertainment industry’s inability to use Beta tapes lead to a domino effect that caused VHS to win, despite the fact it was an inferior format. If Sony wasn’t so self righteous and try to censor the format, the first domino wouldn’t have fallen and chances are, Beta would have won the war. People didn’t need 8hrs of recording (at horrible quality), they really just wanted a home format. The quality and the duration of the tape was an afterthought. On a new subject, who will win, HD DVD or BluRay, this one is easy. NEVER underestimate name brand appeal and catching marketing terms. You can argue which format is better but there are 4 terms that are the cornerstone of high quality entertainment… Plasma, HD, Digital, DVD. The term HD-DVD is uses two of them. People will be drawn to a format they already know (DVD) and people want HD. They may not know exactly what these terms mean, but they know it’s better than what they have now. I fully believe HD-DVD will be a preferred format because the customer already knows these terms and thinks they know the technology.
