What was once a stalemate on the HD format front now seems like a landslide victory for the Blu-ray team. The latest Nielson figures shows that Black Friday really put Blu-ray in the chips. As of this week, Blu-ray now has a 72.6% market share over rival format HD-DVD. The most likely reason for this sudden push in sales was the release of “Live Free or Die Hard”. Despite cheap HD-DVD players, Blu-ray has managed to maintain a sales advantage for quite some time, and currently is holding off HD-DVD with a 2-1 average sales advantage. Last week’s sales advantage was roughly 3-1 in favor of Blu-ray.
