I require data on the size of the market for storage products for CDs
and DVDs.  These are the products that are used to store collections
of CDs and DVDs and are typically either portfolio or tower style. 
Need data for the US market and will take any data available for the
overall world market.  Would also like to the extent possible, sales
data for the major manufacturers as well as the major retailers.  The
major manufacturers are Case Logic, CD Projects, Case-it and Atlantic.
 The major retailers are Circuit City, Best Buy, Wal-Mart, Kmart,
Tower Records and Borders.  I am also interested in both past and
future trends for this category.
