TopSpin writes: "Early this year the meme circulated that Blu-ray might be going the way of Betamax, and for the exact same reason: Sony’s unfriendliness to the porn industry. But at Japan’s recent euphemistically named Adult Treasure Expo 2007, adult filmmakers said Sony has begun offering technical support, and this was later confirmed by Sony PR. The company stated that Sony would offer support to any filmmaker working on the format, no matter their industry. Apparently, Blu-ray is now the preferred medium for Japanese adult films."
