Earlier this month it was discovered that a significant number of movies by Columbia Pictures, a subsidiary of Sony, were mysteriously pulled from the Netflix service offered on Xbox Live – but remained available on other Netflix compatible devices. This of course led many to believe that Sony had carefully timed the downtime of the films as a blow to rival Microsoft on the eve of the NXE launch.
The excuse given by Netflix at the time was that there was a problem with licensing the films for XBLA, claiming they would be back "shortly." Whatever the problem was, it appears that the companies have finally solved it, and now most of the films have been quietly put back up again. Interestingly, Netflix noted that certain Sony titles are still missing and "not necessarily" due to a licensing issue, though no solid explanation was given.
