Netflix might be focusing on its streaming business, but the product that made its name is still alive -- and apparently well. From a report: The company's DVD.com DVD rental business has 3 million subscribers and generated a whopping $56 million in profit on just $99 million in revenue during the first quarter, CNBC is reporting. That staggering profit margin aside, Netflix's business has a wide selection of 100,000 DVDs, which easily overshadows the 5,600 streaming titles available on Netflix, according to the report. DVD.com's profitability might surprise some who moved on long ago from disc-based entertainment in the living room to streaming. Indeed, Netflix itself seemed to have moved on in 2011 when it split the DVD division from its now-core streaming operation. And whenever Netflix discusses its business, the company focuses on streaming and its place in the original content market rather than DVDs.
