Seems like this "Blu-ray" thing is taking off. Likely, as a PS3 owner, you're familiar with the HD movie format. With more and more PS3 systems (and standalone Blu-ray players) entering American households, it was inevitable that Blu-ray sales would continue to grow. According to a report by Home Media Magazine (via Blu-ray.com), revenues from Blu-ray sales increased 68.5% in Q1 2010 vs. Q1 2009, to $331.31 million.

While the format is continuing to grow at a rapid pace, it still has a long way to go before overtaking DVD sales. According to the report, Blu-ray still only accounts for 12.3% of packaged media sales. That's more than the 7% it represented last year, but it's clear that there are many people that have yet to convert to HD movies.
