Although disc sales fell 19% to $14.5 billion, rental revenue remained flat at $7.5 billion. Although it's possible this trend will change as prices for Blu-ray discs approach what consumers are used to for standard DVDs, it may be that people simply don't have an interest in buying the same number of discs as in previous years.
Or it could be a combination of personal collections that are already established and increased competition from products like game consoles. Only time will tell which is a greater factor. Despite the on-going recession, Blu-ray is expected to continue gaining market share in 2009. Perhaps this will be the year we see whether this translates into increased disc sales.
