Netflix experienced some membership turbulence in 2016 as a price increase was phased in for its US subscribers. Over 2015-2016 in Q3, Netflix increased its standard subscription service price from $8.43 to $9.40. By contrast, percentage change in memberships during the same period dropped from 2.5% to 0.9%.

Netflix was trying to implement price increases more slowly after a 2011 increase led to negative publicity and a customer backlash. In that case, Netflix separated its streaming and DVD services, and charged separately for both services.

However, regardless of the implementation of the price increase, the higher monthly prices seem to have impacted the growth of membership among US subscribers.

Calculate price elasticity of demand (PED) for Netflix services and determine if it is elastic or inelastic?
