Generally year to year the period between the 1st and 2nd quarters of the year disc sales slow after the holiday season. This year was not any different for DVD, but Blu ray sales have bucked the trend this year. While over 300 million disc where sold in the last two months of last year, disc sales were also up for the first two months of this year, holding a steady pace equal to the before holiday sales. What is astonishing is the Blu ray market share of some of the biggest titles released this year. Star Trek had a whopping 73% share of the entire disc sales for this title coming from Blu ray. Up was 55% of the entire disc sales coming from Blu ray. Night at the Museum 2 had 68% of the entire disc sales coming from Blu ray, and Inglourious Basterds had 52% of the entire disc sales coming from Blu ray. Blu ray disc sales for the first two months of this year are up 76% over last year at this time. There is no doubt in my mind that Blu ray is no longer a niche product.
