Do you
really know this from the the Post article, or is it from personal experience? Funny, the article made no mention of VHS or Beta.
From the article:
The adoption of Blu-ray Disc by the Japanese porn industry could make all the difference in the format war. The adult film industry has long been a first mover in using new technologies, and many analysts say the industry played a key role in making VHS the winner in the video cassette fight against Sony's Betamax video tape standard years ago. Blu-ray Disc, also a Sony technology, is now vying with HD DVD to be the high-definition disc of choice in the 21st century.
