HD DVD is not only accelerating in growth of sales faster than Blu-ray. Using the number of searches for HD DVD or Blu-ray one can also see how the public are taking interest in the new formats.

According to Google's search results, HD DVD (red) enjoys a comfortable lead over Blu-ray (blue).

Only in Tokyo Japan are things really different, with both formats being neck and neck.

In the UK we see the largest margin, three times as many searches for HD DVD as for Blu-ray.

Again, in the search results we also see the exact same trending that we see on places like Amazon, this helps re-enforce the fact that HD DVD is growing faster than Blu-ray and this isn't just an anomaly in Amazon's salesrank.

I'm not surprised HD DVD is moving ahead, it is the better format. It's cheaper overall, the quality of the video is higher - too many Blu-ray films use MPEG2, where most HD DVDs all use the higher quality VC1. It also supports combo releases, where DVD and HD DVD are on the same disc, it has a larger capacity. It doesn't have as much draconian DRM and it is region free. Plus it comes from the DVD Forum, not a splinter group led by Sony not caring how much they screw the consumer over, by way of format war, slower adoption and confusion, as long as they can get a bigger share of the profits than they would through the DVD Forum.
