The results and analysis for Blu-ray (and DVD) sales for the week ending 28th January 2012 is in. Real Steel was the best selling new Blu-ray release, but the Blu-ray exclusive Paranormal Activity 3 also helped to push Blu-ray revenue higher for the week, at the expense of DVD sales.
Paramount's decision to release Paranormal Activity 3 as a timed Blu-ray exclusive, taking a page out of Disney's playbook, may turn out to be a major milestone for the Blu-ray format. If more studios do the same, then we could see DVD consigned as a "second class" format - although looking at revenue figures, the "Blu-ray exclusive" route might have reduced the amount of money the title might have made had it been available on DVD too - the lack of a combo version that comes in DVD packaging and hence gets displayed amongst the DVD shelves, something Disney always does with its timed exclusives, might have been a contributor.
