An anonymous reader shares a report: On a conference call last October, Netflix Chief Content Officer Ted Sarandos described the hip-hop drama "The Get Down" as a success, like the booming streaming service's other popular shows. Eight months and 11 episodes later, "The Get Down" is history, a flop after one season on the world's largest paid video service. The sci-fi thriller "Sense8," another of the company's lavish productions, was scrapped after two seasons. The back-to-back cancellations caught Hollywood by surprise. Netflix has defied convention by offering no inkling of how many people watch its shows and claiming just about everything is a hit. That's vexed competitors worried about Netflix's growing customer base and influence in Hollywood. The streaming company will spend more than $6 billion on programming this year, a good chunk of that on about 1,000 hours of original shows. Cancellations are common for all TV networks -- even for Netflix, which has wrapped up most of its first crop of original shows. Without the need to attract advertisers, the company is shielded from the weekly audience ratings that determine the fate of most dramas and sitcoms. "One of the great things about Netflix is we don't have to release ratings," Chief Executive Officer Reed Hastings said in an interview this week on CNBC. "Each show gets to have its own audience because it is very personalized." That's great for Netflix and its 100 million customers, who pay up to $12 a month for the service. Without pressure to deliver weekly ratings, the company can give shows time to develop a following. "House of Cards," the thriller starring Kevin Spacey and Robin Wright, just started its fifth season. It's not so great for competitors -- or producers who must grope for ways to measure the success of a given program and wonder if they're getting paid enough by the streaming service. With no data, they must rely on the positive remarks Netflix executives make for all their shows.
