The results and analysis for Blu-ray (and DVD) sales for the week ending 21st January 2012 is in. The Ides of March was the best selling new release of the week, with two other new releases, but none were what you would call A-list, at least according to each's box office takings.
The weekly Blu-ray market share percentage fell to the lowest since September 2011, largely due to the real best seller of the week (when you combine both DVD and Blu-ray sales), Courageous, not doing all that well on Blu-ray.
