Oh what a difference a new release makes to the Nielsen VideoScan charts courtesy of Home Media Magazine. The National Treasure series helped excel Blu to a 7% share this week, which is the second highest we’ve seen since HMM started tracking Blu-ray’s share compared to DVD. The Nic Cage movies took all three of the top spots on the Blu-ray chart, leaving every other title in the dust by a massive margin. But while Book of Secrets may have outsold any other Blu-ray title by almost 4 to 1, it only managed a 6.98% share of the overall title’s sales when compared to DVD. Even though Blu-ray had a great week this week with a 54.94% increase over last, we still can’t help but to harp on the fact that 10 of the top 20 DVD titles aren’t available on Blu. The market share per title chart is back this week (after the jump) and it’s very obvious that Blu makes up for not having the same new releases by selling catalog titles like V for Vendetta and Twister, with the number one title on both the DVD and the Blu-ray top 20, is the number 20th in regards to Blu-ray market share. As for next week, there’s no way Blu-ray can sustain these numbers with only Rambo, but the week after should be really interesting considering how many movies are due to be released on Blu on the same day.
