I am looking for some estimated DVD sales and use information:

Approximately how many DVD?s are sold on eBay annually?

Approximately how many DVD?s does Netflix have in inventory nation
wide? (total number of discs)

I believe netflix sells their excessive inventory on eBay or other
channels after the demand for that title drops off.  Approximately how
many DVD?s does Netflix sell on eBay or through other channels annually?

Approximately how many DVD?s does Wal-Mart have available to rent
nation wide? (total number of discs)

Approximately how many DVD?s are in the entire rental market of North
America? (total number of discs)

Approximately how much does the average family spend on DVD rentals
and how much of it is late fees?

Approximately how many DVD?s have been sold to consumers since their
introduction in 1997?

I saw a chart on http://www.dvdrental.us.com/sidebyside.htm that shows
Netflix with 25,000+ titles available.  Not sure if that is totally
accurate but it is close.

Thank you but that chart lists the number of titles they have
available not the number of discs they have in inventory.
