Rack Jobbing?

I came across this term, "rack jobbing" while reading a book about Music Business.

Rack jobbers are people who lease floor space from stores and put in racks of merchandise.

"Although it looks like Wal-Mart and Target are selling you records, in fact they only turn the space over to someone who decides what products to carry, delivers it to the racks, pays rent to the store, and keeps the profits."

This is certainly something I hadn't considered when walking through a department store, but it makes a lot of sense.
