describe the graph

From 2011 to 2013 total sales of iphones grow rapidly from about 70m to about 150m. Then sales remain stable around 160m from 2014 to 2015.

Looking at the sales breakdown / sales details we notice in 2011 70% of sales were sales to new users then after that the proportion of replacement sales keeps increasing and in 2015 more than 70% of sales are replacement sales.

This may show saturation in the smartphone market
