Some tech urban legends are hard to dispel. Years ago, it was thought the lack of support from adult-entertainment content producers toward Betamax was the reason why Sony ( SNE) lost the video format wars in the 1980s. It's true that Sony didn't work with adult content producers, and the Betamax standard certainly was wiped out by VHS. But that's doesn't necessarily cement a cause-and-effect relationship. However, a similar causation theory has been recently making the rounds that the adult-film industry will drive the next-generation DVD battle between the Blu-ray and HD-DVD formats. And the idea has seemed to gain some credibility because of Sony's refusal to work with the adult entertainment industry. So does that mean the Sony-backed Blu-ray standard will go the way of Betamax? Not likely. This time around, Sony could be making the right moves. The Internet changed the way adult content is viewed and delivered, and what's more, by taking the moral high ground Sony may actually be securing Blu-ray's future. Sony has received much recent flak for its decision to not work with adult-content producers. While it hasn't said it won't allow adult-entertainment content on the Blu-ray format, it has damned content producers by not cooperating.
