The razor-and-blade is popular business model where when you have two complementary products, you sell one cheaply (razor) in order to make more money from the other (blade). Printers (razor) are sold cheaply to attract recurrent revenue from the sale of cartridges (blade). What happens when your blade becomes easily available almost at zero cost to the consumer? This is what happened to the music industry. Artistes on the other hand used concerts to market, sell CDs.
