As Netflix traffic continues to grow, analysts are pondering whether Netflix is a primary driver behind consumers cord-cutting their pay television packages in favor of watching video content online.

A recent article in The New York Times claims that Netflix may be behind the recent decrease in cable television households, citing a report from the Diffusion Group, a media analyst.  The group’s study claims 32% of satellite, telephone, or cable-delivered pay television customers were planning to downgrade or cancel their packages in 2011, a giant increase from the 16% measured in 2010.

Trefis, another research firm, is challenging those assertions, noting an in-depth review of the study finds only around 7% of those planning to pull the plug cited Netflix as the chief reason.

What is causing a rush to downgrade or cancel service?  Rate increases, particularly for add-on services like premium channels or extra tiers including sports and movies.  Time Warner Cable recently boosted prices for HBO to as high as $15 a month for many subscribers.  Netflix may have an impact on these consumers, deciding to drop premium services like HBO, Showtime, and Starz!  For several dollars less than what these premium channels charge, Netflix customers have unlimited access to the company’s streaming video library.

Relentless annual rate hikes have often triggered subscribers to review their packages and delete services to keep the bill stable.  Economic distress is also a widely cited factor among those completely canceling pay television.  The report does not measure how many consumers, especially younger ones, don’t ever start a pay television subscription.  These subscribers never had a cord to cut.
