The results and analysis for Blu-ray (and DVD) sales for the week ending 25th June 2011 has just been posted. It was still a pretty good week for Blu-ray, but nothing like last week, which was the best week in 2 months. The Adjustment Bureau was the week's top selling title, and with 3 other new releases in the top 10, Blu-ray market share remained above 20%.
There were 3 titles that managed to have an above 50% Blu-ray market share this week, and I think one good way to judge the progress of the format might be to see how many titles go above the magic 50% mark, meaning they sold more copies on Blu-ray than on DVD.
